2. Shell Programming and Scripting
In AWK
For 3 individual vectors of the form:
-2.772 -9.341 -2.857
-5.140 -6.597 -1.823
-2.730 -5.615 1.159
I would like to write a script that parses line by line to (i) normalise, (ii) divide by the norm for *each* vector.
I.e.
sqrt(-2.772^2 + -9.341^2 + -2.857^2)=10.154

Hi all, from my understanding I understand that I can use array in this manner.
struct test
{
int a;
int b;
int c;
};
test testing; //creating an array with the structer type
testing.a=1;
testing.b=2;
testing.c=3;
If I'm not wrong we can use array in this manner,... (12 Replies)

Hi all,
I have a vector,the type of the element within it is list<int>,and i wanna sort this vector.So i implemented a function as a predicate for sort(the STL algorithm).Problem came when i missed the bold part in my code,g++ generated lots of error messages.And after i added the bold... (4 Replies)

PLGRADIENT(3plplot) PLplot API PLGRADIENT(3plplot)
NAME
plgradient - Draw linear gradient inside polygon
SYNOPSIS
plgradient(n, x, y, angle)
DESCRIPTION
Draw a linear gradient using colour map 1 inside the polygon defined by the n points (x[i], y[i]). Interpretation of the polygon is the
same as for plfill(3plplot). The polygon coordinates and the gradient angle are all expressed in world coordinates. The angle from the x
axis for both the rotated coordinate system and the gradient vector is specified by angle. The magnitude of the gradient vector is the
difference between the maximum and minimum values of x for the vertices in the rotated coordinate system. The origin of the gradient vec-
tor can be interpreted as being anywhere on the line corresponding to the minimum x value for the vertices in the rotated coordinate sys-
tem. The distance along the gradient vector is linearly transformed to the independent variable of colour map 1 which ranges from 0. at
the tail of the gradient vector to 1. at the head of the gradient vector. What is drawn is the RGBA colour corresponding to the indepen-
dent variable of colour map 1. For more information about colour map 1 (see the PLplot documentation).
Redacted form: plgradient(x,y,angle)
This function is used in examples 25,30.
ARGUMENTS
n (PLINT, input)
Number of vertices in polygon.
x (PLFLT *, input)
Pointer to array with x coordinates of vertices.
y (PLFLT *, input)
Pointer to array with y coordinates of vertices.
angle (PLFLT, input)
Angle (degrees) of gradient vector from x axis.
