if statement - working with characters
显示 更早的评论
I am executing the following code:
x = inputdlg({'Month', 'Population renewal', 'Death rate'}, 'Inputs')
f = getfield(x,{1});
if (f == 'January')
b = 0.5
else
b = 0.7
end
and I am getting an error that says "??? Undefined function or method 'eq' for input arguments of type 'cell'"
Please do tell me where I am going wrong....

Use
if isequal(f{1} ,'january')

Thanks alot for the answer... can you pls explain the logic too so that I can always have it in mind for next time... :)
And also what if I want to say that if f is january, february or march?

f={'january'} % is a cell array
f{1} % is char
'jenuery'==f{1} % the result is the comparison of each character,
isequal('january',f{1}) will compare the two words, the result is 0 or 1
%for you last question
ismember(f,{'janury','march'})

For the comparison of strings, I'd prefer strcmp. This would even accept a cell string as input:
if strcmp(f, 'January')
Or
if strcmp(f{1}, 'January')

any(strcmp(f,{'janury','march'}))
