Output matrix to x/y/cell value

Hey guys,

I'm looking for a little help with a problem that I can't seem to find anyone else having, probably because it's so simple that it can be solved by someone with decent experience very quickly.

I have a matrix with a bunch of numbers. This is not an image, rather the result of calculations for a value of each cell. In all cases, the cell contains either a zero or some decimal value ie 0.006.

What I need to get is an output of three columns; column number(x)/row number(y)/original value of the cell(ie 0.1).

Any help would be appreciated,

Cheers Marty

Hi Martin,

are you looking for something like this:

>> A = rand(2,3)
A =
  0.2020    0.3507    0.0538
  0.2103    0.1068    0.4271

>> [col,row] = meshgrid(1:size(A,2), 1:size(A,1));
>> [col(:) row(:) A(:)]
ans =
  1.0000    1.0000    0.2020
  1.0000    2.0000    0.2103
  2.0000    1.0000    0.3507
  2.0000    2.0000    0.1068
  3.0000    1.0000    0.0538
  3.0000    2.0000    0.4271
