cv1d


Name:
cv1d - convert 2-dimensional coordinates to 1-dim index
Synopsis:
y   x   w  cv1d -> i  

Description:
This function converts a 2-dimensional matrix address to  
the corresponding index of a linear array. Useful if you have to handle
2-dimensional data (e.g. an image) which is stored in a linear array.
Note that by convention the origin is 0,0 and at the upper left corner.

Parameters:
y : integer. the y-coordinate  
x : integer. the x coordinate
w : integer. the border with of the 2-dimensional coordinate system

Example: 3 2 4 cv1d -> 14
3 is the y-coordinate (row)
2 is the x coordinate (column)
4 is the number of columns
14 is the index of the corresponding element in a 1-dimensional array
