In fact I forgot parenthesizing. Is now correct. I need only to fill the gaps with the interpolation by time. The low value after the last gap in this example x (10007) = 469559,65 don't need to be interpolated because was measured. What I need is to interpolate only the gaps (that are variable)
For example for the formula that I want the result for the gaps is:
My need is to automatize this process.

I've become obsessed with trying to get this to work.
As of yet, I am unable to figure it out. Unfortunately, I don't have Linux or UNIX available when I get home.
Anyone have tips for me on how I can pass param1 to ID via use of COUNTER and loop?
thx.

Hi everybody,
Firstly, this would be the first time I'm using JavaScript. My background is mainly Perl. Nevertheless, here's my problem.
So I've created a function
function linkout(url){
setTimeout("window.open(url)",5000) //in milliseconds
}
However because the variable "url" is... (0 Replies)
Hi,
I have a snippet like below.
Based on variable i, i wish to print 1,2,3,4,5th columns to Sample files.
For each loop, one column from contetn and results will be pused to sample files. But i have a problem here

Hi all,
Consider I have a text file containing:
1003 60
1005 80
1100 110
Based on that file I need to create another file which is containing value from 1001 till 1100 which is a linear interpolation between two point (for 1004; 1006;1007 until 1109) and extrapolation based on 2... (7 Replies)

Dear All,
I have two files which contain numerical data and strings. I want to create a new file that only revise numerical data from two files using interpolation. I guess AWK works, but I am new on AWK.

Dear all,
I always appreciate your help. I am an electrical engineer. I am using a tool for timing analysis of a circuit. I would like to interpolate results from two timing reports at different voltages (0.945V and 0.78V). If voltage is decreased, data arrival time is increased.

filter1d
FILTER1D(l) FILTER1D(l)
NAME
filter1d - Time domain filtering of 1-D time series
SYNOPSIS
filter1d [ infile ] -F<type><width> [ -Dincrement ] [ -E ] [ -H[nrec] ] [ -Iignore_val ] [ -Llack_width ] [ -Nn_cols/t_col ] [ -Qq_factor ]
[ -Ssymmetry_factor ] [ -Tstart/stop/int ] [ -V ] [ -bi[s][n] ] [ -bo[s][n] ]
DESCRIPTION
filter1d is a general time domain filter for multiple column time series data. The user specifies the number of columns of input and which
column is the time. (See -N option below). The fastest operation occurs when the input time series are equally spaced and have no gaps or
outliers and the special options are not needed. filter1d has options L, Q, and S for unevenly sampled data with gaps.
infile Multi-column ASCII (or binary, see -b) file holding data values to be filtered.
-F sets Filtertype, type is one of b(oxcar), c(osine arch), g(aussian), m(edian), or p(maximum likelihood Probability estimator -- a
mode estimator), and specify full filter width in same units as time column, OR, use -Ffname to give the name of a one-column file
of your own coefficients. Upper case type B, C, G, M, P, F will use robust filter versions: i.e., replace outliers (2.5 L1 scale
off median) with median during filtering.
OPTIONS -D increment is used when series is NOT equidistantly sampled. Then increment will be the abscissae resolution, i.e., all abscissae
will be rounded off to a multiple of increment. Alternatively, resample data with sample1d.
-E Include Ends of time series in output. Default loses half the filter-width of data at each end.
-H Input file(s) has Header record(s). Number of header records can be changed by editing your .gmtdefaults file. If used, GMT default
is 1 header record.
-I To ignore values; If an input value equals ignore_val it will be set to NaN.
-L Checks for Lack of data condition. If input data has a gap exceeding width then no output will be given at that point [Default does
not check Lack].
-N Sets number of columns in input and which column contains the independent variable (time). The left-most column is # 0, the right-
most is # (n_cols - 1). [Default is n_cols = 2, t_col = 0; i.e., file has t, f(t) pairs].
-Q assess Quality of output value by checking mean weight in convolution. Enter q_factor between 0 and 1. If mean weight < q_factor,
output is suppressed at this point [Default does not check Quality].
-S Checks symmetry of data about window center. Enter a factor between 0 and 1. If ( (abs(n_left - n_right)) / (n_left + n_right) ) >
factor, then no output will be given at this point [Default does not check Symmetry].
-T Make evenly spaced timesteps from start to stop by int [Default uses input times].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-bi Selects binary input. Append s for single precision [Default is double]. Append n for the number of columns in the binary file(s).
-bo Selects binary output. Append s for single precision [Default is double].
EXAMPLES
To filter the data set in the file cruise.gmtd containing evenly spaced gravity, magnetics, topography, and distance (in m) with a 10 km
Gaussian filter, removing outliers, and output a filtered value every 2 km between 0 and 100 km, try
filter1d cruise.gmtd -T0/1.0e5/2000 -FG10000 -N4/3 -V > filtered_cruise.gmtd
Data along track often have uneven sampling and gaps which we do not want to interpolate using sample1d. To find the median depth in a 50
km window every 25 km along the track of cruise v3312, stored in v3312.dt, checking for gaps of 10km and asymmetry of 0.3, try
filter1d v3312.dt -FM50 -T0/100000/25 -L10 -S0.3 > v3312_filt.dt
