What does this error mean and how can it be solved. 'Unable to perform assignment because the size of the left side is 1-by-2091 and the size of the right side is 1-by-2092'

Im getting the following error when I try to perform CCA on a 2097 x 3 data matrix. 'Unable to perform assignment because the size of the left side is 1-by-2091 and the size of the right side is 1-by-2092'.

Im using Dr Van Der Maatens drtoolbox. What does the error mean and how do I fix it?

Please assist.

Some where you try to do:

x = something;

where x is predefined to be 1x2091 vector, and something is a 1x2092 vector.

So my suggestion: check where the code sets the size of x, because probably it's of the wrong size. You might want to report the error with the writer of the toolbox.
