Hi All, Please help with the following problem. I am trying to do the following: N=A^(-1)BZ where A is a 29×29 matrix and B is a 29×13 matrix. I have created these matrices as AA and BB, respectively in the attached file. While MATLAB created the AA matrix, it is giving me the following error when it comes to run the BB section: Error using vertcat CAT arguments dimensions are not consistent. Thanks for your help.

3 means the 2-D arrays are being stacked along the 3rd dimension. To visualize, imagine that the arrays are gray scale images in the x-y plane. Now you use cat() to stack them vertically along the third, Z, dimension. See image below, and attached demo script.
The 3-D image above would represent a color image.
Another case could be where you have lots of images, like slices from a CT or MRI scan. These images, stacked along the 3rd dimension would represent a volumetric images.
If the number were 4, then it could mean that you're stacking 3-D (color) images along the 4th dimension (representing time) to create a movie.
Does that explain it sufficiently to you?
