I am transforming my m file for compliant to the embedded matlab function. but I didnot solve that error messages :

t=0:comp_range*comp_ratio/comp_range:comp_range*comp_ratio;
message : Operands must be constants.

"but these operands are inputs of the block and this is the real time application, so they must change. "

and

k.01;
y = fft(bp_sound_mix((k:k+499),:),4096);
message: could not determine the size of this expression (k:k+499)

"I didnot understand the message logic"

so what can I do for that messages ?

thanks

Instead of

k:k+499

use

k + (0:499)
