Thank you but it is not working for my image.I am explaining it in detail.I have drawn a sine wave in paint where the x-axis is representing the number of columns and y-axis is representing the number of rows. The number of columns is from 1 to 600 and the number of rows is from 1 to 100.Then I have read it in matlab.Now i need to find the peak coordinates of that sine wave. I am attaching the image of the sine wave.Kindly help me
