Definite Integral for known matrix

Hi,

I have a matrix P(x) and x, both are known. I need to find a definite integral between a to x of (P(x).dx)). How can I do that? Is there a way I can use seperation of varables here?

Is P a matrix of symbolic expressions? If so then

int(P, x, a, x)

matlab is showing int as an unrecognized function....

int() requires the Symbolic Toolbox and the first parameter must be class sym or symfun
