Is it possible to set SINGLE PRECISION as default for a hole program?

I need to have all the variables in my program with a single precision. How can I set it as default, for avoiding to use the command 'single' for each of my variables?

By default, MATLAB stores all numeric values as double-precision floating point. You cannot change the default type and precision.

But still you may be able to generate single-precision MATLAB code from double-precision MATLAB code. This may require MATLAB Coder and Fixed-Point Designer along with MATLAB.

You can take a look at the following link fore more info:

Hope this helps !

Hi Robin,

Can one follow the process suggested in your link even when if the program depends on extensive (third-party) Matlab toolboxes (SPM in this case: http://www.fil.ion.ucl.ac.uk/spm/ )

I am looking for a way to speed things up, in case you have some other suggestions.

Many thanks and best wishes, Stavros
