How can iget over this error message "Matrix dimensions must agree'. i am trying to obtain the value of w1, 2,3,4.

rx = r*cosd(psi);
ry = r*sind(psi);

r1_half2 = sqrt(power(b/2-ry,2)+power(rx-t/2,2));
r2_half2 = sqrt(power(b/2-ry,2)+power(rx+t/2,2));
r3_half2 = sqrt(power(b/2+ry,2)+power(rx-t/2,2));
r4_half2 = sqrt(power(b/2+ry,2)+power(rx+t/2,2));

theta = [theta_half1 0 theta_half2];

r1 = [r1_half1 -psi r1_half2];
r2 = [r2_half1 -psi r2_half2];
r3 = [r3_half1 psi r3_half2];
r4 = [r4_half1 psi r4_half2];

rmsws=input('rmsws');
rmsr = power((power(rx,2)+power(ry,2)+0.25*(t*t+b*b)),0.5);


w1 = rmsws*(r1./rmsr);
w2 = rmsws*(r2./rmsr);

Dimensions of r1 are 1x3, whereas the dimensions of rmsr are not obvious, but it seems to be the same as size(psi). These two dimensions do not match, so you cannot divide the elements of these two vectors.

The reason for above error is mistach of matrix size.

While performing a dot divison operation the matrix size should match

check the size of two matrixes using size function

a=size(r1);
b=size(rmsr);
% a should be equal to b
