The tool you are looking for is HDL Coder. You can use MATLAB's ver command to see if you have HDL Coder installed. If you do have it available I recommend reading the introductory documentation and working completely through a couple of the provided examples so that you can get a feel for using the tool, and for the style of MATLAB code that can be converted to HDL.

It appears to me that the Fixed Point Toolbox will also be needed for the above code.
Note: HDL will not support graphics.

Hello sir,
Can you please help me to get the space vector pulse width modulation for the case of 4-phases, please ?
i need it for my final year project for master graduation.
Thank you
