I have a 74x99 matrix and i want to make animation from contour with using get frame in certain range ( for example from zv_avg( :,20) to zv_avg (:,85) ) when i write this code below it gives me only contourf(zv_avg,contourlev)

addpath('G://exports/60z1j28v')
load('zv_avg.mat')
contourlev=[-0.0025:0.0002:0.01];
figure
clf
for k=1:99
    zv_avg_time= zv_avg(:,k);
    contourf(zv_avg,contourlev)
    title('zv_animation')
    drawnow  
end

contourf(zv_avg,contourlev)

In the above command, you are not changing anydata, how you expect to get an animation?

Are you looking for this or else?

addpath('G://exports/60z1j28v')
load('zv_avg.mat')
contourlev=[-0.0025:0.0002:0.01];
figure
clf
for k=1:length(contourlev)
    zv_avg_time= zv_avg(:,k);
    contourf(zv_avg,contourlev(k))
    title('zv_animation')
    drawnow  
end

Or

addpath('G://exports/60z1j28v')
load('zv_avg.mat')
contourlev=[-0.0025:0.0002:0.01];
figure
clf
for k=2:99
    zv_avg_time= zv_avg(:,1:k);
    contourf(zv_avg_time,contourlev)
    title('zv_animation')
    drawnow  
end

i don't want to change contour levels , what want to change is number of columns , program should consider 2 column at each time to draw contour and this will continue up to end (99. column) and i will get frames of these contour to make a animation
