Thank you. this solution works and does exactly what I really needed. The interpolation is just alright. As you can see this is time series data for some quantity that depends on the sun, which exhibits higher values during the day that at night. this is morning and the variation of the quantity more complex due to too many factors. So this interpolation does just fine. I have just increased the precision of the D0/D1 to include more significant figures and that solves the problem you indicated with the
.
Again may I say thank you and am sure this will help others as well.
Hi,
I have two time series data (below) merged into a file.
t1 and t2 are in unit of second
I want to calculate the average of V1 every second and count how many times "1" in V2 is occur within a second

Hi Experts ,
I need your help to collect the complete data between two time frame from the log files, when I try awk it's collecting the data only which is printed with time stamp
for example, awk works well from "16:00 to 17:30" but its not collecting <line*> "from 17:30 to 18:00"

mtbl_varint
MTBL_VARINT(3)MTBL_VARINT(3)NAME
mtbl_varint - Variable-width encoding and decoding of 32 and 64 bit integers
SYNOPSIS
#include <mtbl.h>
unsigned mtbl_varint_length(uint64_t value);
unsigned mtbl_varint_length_packed(const uint8_t *buf, size_t len_buf);
size_t mtbl_varint_encode32(uint8_t *ptr, uint32_t value);
size_t mtbl_varint_encode64(uint8_t *ptr, uint64_t value);
size_t mtbl_varint_decode32(const uint8_t *ptr, uint32_t *value);
size_t mtbl_varint_decode64(const uint8_t *ptr, uint64_t *value);
DESCRIPTION
mtbl_varint_encode32() and mtbl_varint_encode64() write the 32 or 64 bit quantity, respectively, in the argument value to the buffer in the
argument dst. The quantity will be written in using a variable-width encoding that uses at most 5 bytes for a 32 bit quantity or 10 bytes
for a 64 bit quantity.
mtbl_varint_decode32() and mtbl_varint_decode64() read the 32 or 64 bit varint quantity, respectively, in the argument ptr. The quantity
read will be placed in the argument value.
Bounds checking must be performed by the caller.
RETURN VALUE
mtbl_varint_encode32() and mtbl_varint_encode64() return the number of bytes written to dst.
mtbl_varint_decode32() and mtbl_varint_decode64() return the number of bytes read from ptr.
mtbl_varint_length() returns the number of bytes that its argument value would require in the variable-width encoding.
mtbl_varint_length_packed() returns the number of bytes consumed by the variable-width encoded quantity at its argument data. It will read
at most len_buf bytes from data. The value 0 is returned if a valid varint is not present.
