Hello everyone

I wanted to store all winter ("Win") values of the rrr24 column in my data set in a new array

So I tried to do it like:

C_Winter = temp(strcmp((temp.seasons,'Win'),rrr24));

But this error appears,

 C_Winter = temp(strcmp((temp.seasons,'Win'),rrr24));
                                            ↑
Error: Invalid expression. When calling a function or indexing a variable,
use parentheses. Otherwise, check for mismatched delimiters.

I tried some other ways but all of them leads to error. Do you know what should I do?

Thank you.

The above is all columns, you said you wanted the one variable...alternatively, remove the string from the 'seasons' variable...

temp.seasons=categorical(temp.seasons);         % convert to categorical variable type
C_Winter=temp.rrr24(temp.seasons=='Win');       % pick winter seasons from rrr24 array
