my code is here%%STEP FIRST (wave form)
clc;clear all;Imax=0.8;Imin=0.2;Im=Imax-Imin;T = 20;s1= @(x) ((2*Im*x/T)+Imin+Im/2).*(0<=x & x<=T/4) +((-2*Im*x/T)+Imin+3*Im/2).*(T/4<=x & x<=3*T/4)+((2*Im*x/T)+Imin-3*Im/2).*(3*T/4<=x & x<=T);x = linspace(0, 20);I1 = s1(x);figure(1),plot(x,I1)% second step (2D matrix image)
m=1000;n=1000;for i=1:m for j=1:n s1= @(x) ((2*Im*x/T)+Imin+Im/2).*(0<=x & x<=T/4) +((-2*Im*x/T)+Imin+3*Im/2).*(T/4<=x & x<=3*T/4)+((2*Im*x/T)+Imin-3*Im/2).*(3*T/4<=x & x<=T); I(i,j)=s1*(j/n+i/m); endendimshow(I,[]);
second step is not working, where is wrong? please help please find attachment
