MATLAB: Matrix dimensions must agree error.

Question

loop5=0;
while~loop5
  parameters=input('Parameters Data( manufacturer or test ) = ','s');
  if ~ismember(parameters,{'manufacturer','test'})
      loop5 = 0;
else loop5 = 1;
end
end
if parameters == 'test'
    disp('Test Data');
    Pnl=input ('No load power input= ');
    Inl=input ('No load line current= ');
    Pbr=input ('Lock rotor power input= ');
    Ibr=input ('Lock rotor line current= '); 
elseif parameters == 'manufacturer'
    disp('Manufacturers data');
    R1=input('R1= ');
    R2=input('R2= ');
    X1=input('X1= ');
    X2=input('X2= ');
    Rc=input('Rc= ');
    Xc=input('Xc= ');
else
end
If I will input manufacturer Matrix dimensions must agree error appear.
Thank you for your help

Answer 1

I cannot run your code to test this.

Try:

if ~strcmp(parameters,{'manufacturer','test'})
