Difference between size '[:140 x 1]' and 'size [140 x 1]'

Diagnostics says:'Size mismatch. Input 2 expected value of size [:140 x 1]. Found size [140 x 1].'

what is the difference between '[:140 x 1]' and 'size [140 x 1]'?

Probably you should transpose the result and use as input.

I assume this is what you get in your code generation report? [:140x1] means that the signal is a column vector with an upper bound of 140 elements, i.e., it could change but has at most 140 elements. On the other hand, [140x1] means the column vector is fixed size with 140 elements in it. You can find more information in the following link
