equation

How would you integrate he following equation in matlab:

Zv=int_{0}^{zd}(z*Az*dz)

where dz refers to integrate with respect to z; zd=20; z=depth for the measurement (which is a column vector); and Az= area at depth of measurement (also a column vector). So, basically I should obtain a vector for Zv from integrating between 0 to zd for z*Az with respect to z.

thanks

cumtrapz(z.*Az)  % assuming z & Az are numerical column vectors
