Multiplying a string with 1 or 0

7 views (last 30 days)
Check_B = 0; % checks if condition for B is satisfied
string = strcat('A', Check_B*'+B')
I want to be able to add one string to another only if a condition is satisfied, without making an if statement or switch statement.
If Check_B = 0, ('+B') will not be added, otherwise it will be.
The code provided works, however it gives a warning.
Is there a cleaner way to do the same? (I believe this is possible in Python for example)

Here is one way:
c = ['A', repmat('+B',Check_B)];
Be aware that you are actually working with character arrays, not strings.

And also, that by naming your variable 'string' you are hiding the actual string functionality of Matlab by your variable, which is never a good idea.
