hi, i have written a code in editor to find a value ,'phase_delay'

    ip = menu('input is','ac','dc')% askin whether input is ac or dc
if ip==1
    Vdc=inputdlg('dc output needed = ');
cos_alpha=((Vdc*pi)/(220)-1);
alpha=acosd(cos_alpha);
phase_delay=(alpha)/18000
end

now i want to put this value of phase_delay in "phase delay" of simulink/sources/pulse generator, automatically.

Side question: what should be done if "ip" is _not_ 1 ?

Also, is it correct that you prompt for the DC output needed only when the user selects AC (the first option, ip == 1) ?

so sorry ,

please take ac as default ie ip==1, always

在 MATLAB Online 中打开

Do you want to set it on a model that is already open? If yes, you can use the set_param command:

>> set_param('path/to/block', 'PhaseDelay', num2str(phase_delay))

Note that phase_delay needs to be converted to a string using num2str because set_param needs the value to be set as a string.

@kaustubha govind ,is there any any way to update the value of phase delay in pulse generator block in simulink.

i mean, using subsystem masking in simulink i m changing the value of a variable according to my need , now i want that simultaneously the value of phase delay changes it self,proportional to change in variable.

or tell me whether it is feasible or not,

PLEASE ,PLEASE DO REPLY
