The value of j goes upto 1025 but i stays at 255 itself ,what's the error in this nested loop??
X = load('x.mat');
Y = load('y.mat');
for i=245:61503
i = i+10;
for j=1:1024
j=j+1;
figure(); hold on
plot(Y.y(1:i,j))
set(0,'DefaultFigureWindowStyle','docked')
end
end
hold off

Alright I have x =1x1024 and y = 61503x1024 matrices
X =x,Y=y
I'm trying to plot a 2D plot and 3D plot for it at every 10th step:
Like for y 1:247 and then y 247:494 till 61503 , x goes as 1 and linearly to 1024
so the normal plot goes as for 2D : plot(Y.y(1:247,1) for the first plot and goes on
I would like to convert this data to 3D values and then plot surf for it.
May be not for all the values just for 1,mid value and end value.

Why are you putting j = j+1? There is no need to put it with matlab.
X = load('x.mat');
Y = load('y.mat');
for i=245:10:61503
for j=1:1024
figure(); hold on
plot(Y.y(1:i,j))
set(0,'DefaultFigureWindowStyle','docked')
end
end
hold off
By the way, 245+10*n is never going to be 61503

Alright matlab crashes for sure :) due to rendering issues.
