MATLAB: Can’t I solve this, it’s simple. (Incorrect dimensions…. use .^) (I did then it says Invalid Operator…….)

invalidMATLABoperator

>> [x,y]=meshgrid(1:1:exp(5), -3:0.01:3)

>> z=((x+1)^y)-(x^y)

Error using ^ (line 51)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a

scalar. To perform elementwise matrix powers, use '.^'.

>> z=((x+1)^.y)-(x^y)

z=((x+1)^.y)-(x^y)

Error: Invalid use of operator.

This works fine:

z = ((x+1).^y)-(x.^y);

You should read a bit on the difference between array and matrix operations.

Do change

C1=[1 0 -(n_zx*(alpha_x+beta_x*S)*((z)/(z_x))^(-1+n_zx)/(1+S+(z/z_x)))];

In the following x is not define, you trying to access x as array

C2=[1 0 (x(2)/y_z)^n_yz-delta_z*x(3)];
%........^.......................^....

In the intial line

syms z y z
%....^...^ same ...is it x?

Remove the z=x^2 from the loop.

syms x n y z a;
n= 5
z=x^2;
for y=1:n
 
 z=int(z)
 
end
