Make an attempt. We will correct you if something is wrong.

In your workspace, h is listed as a function handle. You can call this function handle as h(i,j) and it will return a double evaluated at theta=i and z=j, but you cannot set this value to another double value, namely ((1+E*cos(theta(i)))...

What you could do in the loop is to write

H(i,j) = h(theta(i),z(i));

instead of

h(i,j) = ((1+E*cos(theta(i)))...

and continue working with the array H consisting of doubles.

Note that MATLAB uses period for decimal. X=0.0 not X=0,0
