matlab - Writing 2 variables in a legend with 2 different plots

Question

I want to write 2 variables in my legend.

legend('raw', 'suggested-signal: %f , suggested-filter: %f',a,b);

I know this is wrong, but I don't know how else to include 2 variable in the legend. I have a way for 1 variable but not two.

Answer 1

If I get your intention correctly, you miss the sprintf:

legend('raw', sprintf('suggested-signal: %f, suggested-filter: %f',x,y));
