Can I change the SVM classifier output from 'true', 'false' to 0,1?

Hi Can I change the SVM classifier output from 'true', 'false' to 0,1? as i am currently get the output in the form of true and false and it is better for my problem domain to have it in 0 and 1. i write a code to string compare but it takes too long as i have a great amount of data. so if there is anyway to change the output of the classifier to give 0 for the 'false' classifications and 1 for 'true' ones. thank you for your time regards Emad

Add 0 to your output.

true + 0

is 1, and

false + 0

is 0

Or, for many purposes, you can just go ahead and use the logical values in numeric statements.

true * 5 / (false + 1)

Not everything, though: for example, exp(false) will not work, but exp(false+0) will work.

You can cast it to double, try this:

x = [true false true true];
y = double(x);
