Hello everyone, I tried many ways to adjust the view of the colorbar to the same view of the fill image, but failed.
%%
x = 100*rand(100,100);
contourf(x,'Linestyle','none');
set(gca,'view',([5,30]));
axis([0 100 0 100 0 1]);
c = colorbar;
%%
it looks like the position of the colorbar in the figure below,is there any way to solve it?

You may want to create the colorbar yourself that attached to the data as follows:
n = 50;
x = 100*rand(n,n);
% Add the custom colorbar by extending the data
% gaps of 2 | color bars with width if 2
x = [x nan(n, 2) repmat(linspace(1,100,n)', [1 4])];
contourf(x,'Linestyle','none');
set(gca,'view',([5,30]));
box off
axis off

try that adding the colors to the image and add artificial labels using text
close all;
x = 100*rand(100,100);
contourf(x,'Linestyle','none');
c = colorbar;
climits=c.Limits; % get limits of original colorbar
x=[x repmat(linspace(climits(1), climits(2),100)',[1 10])]; % add colorbar to image itself
contourf(x,'Linestyle','none'); % plot again
axis([0 110 0 110 0 1]); % extend view to 110 to see the artificial colorbar of width 10
view([5 30]); yticklabels([]); % remove ylabels so we can add our colorbar labels at the position % alternatively you can also edit the yticklabels and inserrt the values from the text() function below
labelPos=0:10:100;
labelVal=linspace(climits(1),climits(2),numel(labelPos));
for labelNr=1:numel(labelPos)
text(115,labelPos(labelNr),0,num2str(round(labelVal(labelNr)))); % add text labels near colorbar
end
xticks(0:10:100); % to prevent the 110 tick value which is not part of the original image
