How to calculate execution time of for loop inside the Math function block?

for k = 1:16
    state=[  1  0  1  0  1  0  1  0  ;  
            1  0  1  0  1  0  0  1  ;  
            1  0  1  0  0  1  1  0  ;  
            1  0  1  0  0  1  0  1  ;  
            1  0  0  1  1  0  1  0  ;  
            1  0  0  1  1  0  0  1  ;  
            1  0  0  1  0  1  1  0  ;  
            1  0  0  1  0  1  0  1  ;  
            0  1  1  0  1  0  1  0  ;  
            0  1  1  0  1  0  0  1  ;  
            0  1  1  0  0  1  1  0  ;  
            0  1  1  0  0  1  0  1  ;  
            0  1  0  1  1  0  1  0  ;  
            0  1  0  1  1  0  0  1  ;  
            0  1  0  1  0  1  1  0  ;  
            0  1  0  1  0  1  0  1  ];

      Si1=state(k,1);
      Si3=state(k,3);
      Si5=state(k,5);
      Si7=state(k,7);
  .............

    g = abs(irefa-io_p_a) + abs(irefb-io_p_b) + abs(irefc-io_p_c)+lambda_sw*abs(Si7-Si7_prev);
      if (g<g_opt)

Hi,

have you tried using tic & toc functions?

hi, facing the attached error.

[Walter Roberson]

Is the code generation being done because you are using one of the accelerator modes to run faster on your host? Or is code generation being done as part of deployment to hardware such as Raspberry or Arduino?

[Abdul Mannan Dadu]

The coding inside Math function has given. if i use tic-toc ,the above error shows.How can I calculate the execution time of for loop...Thanks

[Grégory SEABRA]

If you use the tic toc fonctions in a math function block, you must output the toc result out of this block, otherwise you won't be able to visualize it as you put ";" after them..

Furthermore, you might not be able to simulate in accelerator or rapid accelerator mode because it generate code from this function...

[Walter Roberson]

Are you using any accelerator mode other than "normal"? Or are you trying to deploy to a hardware device, and if so then which one?

We need this information in order to be able to figure out the appropriate replacement timing mechanism for your situation. We could tell you to just toss in the coder.extrinsic('tic') and coder.extrinsic('toc') like in the error message, but that will only work for the "normal" and "accellerator" mode and not for rapid accelerator mode and not for deployment to hardware.
