**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
