Hi all In the GUI in matlab i am creating a single sin wave with a freq between 1KHz-15Khz in steps 1KHz. In matlab iam using the fft() function to get the freq specturm and then get mag and find the peak which will give me the freq. But i need to make a GUI version of this and cant seem to get any thing to work . can anyone help or give me a website to look at. Thanks James_Bond
Using fft() in Guide MATLAB- HELP PLEASE

I don't understand what you mean when you say: "i am creating a single sin wave with a freq between 1KHz-15Khz in steps 1KHz." I could understand if the steps in the sinusoid were 0.03msec but not steps measured in kHz! I took it to mean that a "single sin wave" would be in the form of sinwt. Perhaps you mean a "stepped frequency sin"? All that aside, what is your problem / objective? That's not clear. Fred
