MATLAB: How to solve this error ‘Subscripted assignment dimension mismatch.’

assignment dimension mismatchsubscripted

Hi, guys please can someone help me resolve why the below code returns the above mentioned error.
N = 100;
z1 = zeros(1,N);
z = meshgrid(z1);
p = meshgrid(z1);
for ii=1:length(aa)  
  xn=linspace(-aa(ii),aa(ii),N); yn=linspace(-bb(ii),bb(ii),N);  
  for i=1:length(xn)    
    for j=1:length(yn)      
      z(i,j) = (1 - (xn(i)/aa(ii))^2 - (yn(j)/bb(ii))^2);
      if z(i,j)<0
        z(i,j)=0;
      end      
      p(i,j) = 1.5.*F_N.*(pi*aa(ii)*bb(ii))^-1*sqrt(z(i,j));
    end
  end  
end

Best Answer

I’m guessing this line is throwing the error and it is because ‘F_N’ isn’t a scalar:
p(i,j) = 1.5.*F_N.*(pi*aa(ii)*bb(ii))^-1*sqrt(z(i,j));
