Hi all,
Is it possible to assign values (variables) to elements in a matrix that is defined as a function handle?
For example:
prop1 = zeros(2);
prop1(:,1) = 1;
prop1(:,2) = 2;
prop1
prop1 = 2×2
1 2 1 2
prop2 = @(x) [0 0;
0 0]
prop2 = function_handle with value:
@(x)[0,0;0,0]
prop2(:,2) = @(x) x(2)
Nonscalar arrays of function handles are not allowed; use cell arrays instead.
I would like to assign variables to prop2 as I did to prop1.

Is it possible to write the following function handle with less effort? Maybe with a couple of code lines.
prop = @(x) [x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(1) x(3) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0;
x(2) x(4) 0 0];
