I have the following Code:

[row_inst_5(:,:,image), col_inst_5(:,:,image)] = find(BB_inst(:,:,image));

The input to the "find()" command is a 137x145 Matrix.

When I run the code it outputs a 138x1 matrix for both "row_inst_5" and "col_inst_5" which is incorrect based off the "find()" guidlines in the Matlab explanaion on how to use the "find()" command. This is an issue because when I run this in a loop of images from 1-93, 1-8 will be the correct size (137x1) while 9 will be the incorrect size (138x1). This is an issue because my loop then errors.

How can I fix this issue?

Thanks for your help.

Is there a way I can do this through logical indexing? BB_inst is jet a matrix filled with zeros and ones and I just want to find the location of matrix elements that are greater than zero..
