matrix - Access to submatrices in symbolic writing (matlab) -

considering matrix defining using symbolic toolbox:

   syms x y    f(x,y)=[1 x x^2; 1 y y^2];

we obtain:

   >> f(x,y)     ans =     [ 1, x, x^2]    [ 1, y, y^2]

how can extract second row of matrix? indexing scheme different in case (f(x,y)(2,:))?

you have defined (scalar 1x1) symfun returning matrix, there no indexing directly on symfun. extrat symbolic term first:

%convert symfun sym f=f(x,y) %now can use indices f=f(1:2,3) %convert symfun f(x,y)=f
