Convert a wave image to x-y function

imwtoxy functions to convert an image captured from an oscilloscope to its x-y function

function [x,y]=imwtoxy(signal,V,T,px)

imwtoxy functions can be used to convert an image of a wave captured from

an oscilloscope to its x-y representation Which may be use

to find mathematical properties of the wave by matlab functions.

The Simple codes of input data are:

Signal = image names with its kind.... example 'wave.jpg'

V = Volt per div in the oscilloscope panel

T = Second per div in the oscilloscope panel

px = Number of pixel per centimeters in the oscilloscope grid image

x = Time vector of the result AC voltage wave

y = Alternating amplitude vector of the result AC voltage wave
