Hi all,

I using MatLab 2016a and I am trying to create if loop however, always get the following error "Undefined operator '==' for input arguments of type 'cell'.

I undersand its cell array not character but even if i change p to character still not working... hope anyone can help me... I just would like to do a statement if p='yes' and another if something else and so on...

clear all;
clc;
p={'yes' ,'no'};
for i=1:2
    if p(i)=='yes'
            z(i)=1500+(3/4)
    else 
            display('wrong')
    end 
end

在 MATLAB Online 中打开

p={'yes' ,'no'};
for i=1:2
    if isequal(p{i},'yes')%need {} instead of (), use isequal()
            z(i)=1500+(3/4)
    else 
            display('wrong')
    end 
end
