Cannot calculate a definite integral of a matrix

Hello,

I encountered another problem in Mathcad 15. I want to calculate a definite integral of a matrix (to be more precise, Mathcad should automatically calculate a definite integral of each matrix entry). I am getting an error "this calculation does not converge to a solution". However, when I manually define the definite integral of each matrix entry, Mathcad 15 obtains the solution without a problem. In the attached example the matrix size is 2x2, however my calculations will deal with few dozens of matrices with sizes varying from 6x6 to 15x15 (user defined size). Obviously I want to avoid typing 36 or even 225 integrals manually. Does anyone know a solution to this problem or yet another Mathcad bug? Thank you in advance for your help.

Best regards

Rafal
