vectorise() go to deep without first calculating the matrix product

vectorise() go to deep without first calculating the matrix product - I think it should multiply the matrices first and then apply the comparison per line. - Сообщения

I think the vectorize() command goes too deep in the example. Probably it takes the first row from the first matrix, then it probably tries to multiply it with the second vector. Then I get the error message: Number of rows and/or columns of matrices or vectors do not match.

I think it should multiply the matrices first and then apply the comparison per line.

Can somebody take a look at this, please?

Maybe this is a simple way to solve the problem

Thank you both for the quick answer! I didn't know there was an eval() function. I now understand that SMath resolves everything as low as possible and then calculates in one go. The use of eval() in the right place prevents this.
