I have a number N_train that I want to convert to a single quotes string (otherwise the title does not look as I want it):
title_name = ['Training data' string(N_train)]
though string returns a double quotes representation of the string for some reason. I tried making the first string double quotes but it doesn't fix it.
Is there a way to cast to single quotes strings in matlab?

single quote string is actually a char array. They were the only kind of strings available pre-R2016b. Anyway, to get a char array:
title_name = sprintf('Training Data %d', N_train);
or
title_name = compose('Training Data %d', N_train);
To get a string:
title_name = compose("Training Data %d", N_train);

Yes, you can use the function char() to convert your string

char will not convert a number to its char array representation (which is what is asked here).
