How to change the real_T in generated C code to be float type?

Hi, I am now using Matlab2015b. I use the Code Generation of simulink to convert the algorithm inside Matlab Function into C code. In the generated code, I found that the real_T is float, as shown below
typedef doulbe real_T;
However, I hope that real_T could be float, so that the calculation time needed inside my ARM chip could be saved a lot.
I know that one method is specifying every variable with single() function, but there are so many variables inside my algorithm. So is there some other better methods? Thank you.

have you tried replacing double by float in that typedef statement?
typedef float real_T;

No problem. Not sure if there is a setting in matlab that allows you to specify whether you want single or double precision. If you find any, please share it here :)
