How to plot a table in a way that first column and first raw are x and y axis?

Hello

I have a table of data in csv format (shown below) and want to plot them in Matlab using surf function. First column and first row are the x and y axis. Middel onse are collected data. It seems reading raw is a problem in Matlab. Can anyone suggest an easy way to plot such a table? All my tries failed :(

my data look like this in csv file:

0            100      200      300    400
330         53        45        76      22
340         21        34        32      87

A = readmatrix ('Y1.csv');
x = A(:,1) ; 
y = A(1,:) ; 
z = A(2:end,2:end) ; 
z = transpose(z)
    surf (x, y, z)
    shading interp

There is no data for the (0,0) coordinate so it can't be in the X,Y vectors---and the Z array must be size(Z)-->[m,n] where X,Y correspond to [m,n]. IOW, you don't transpose...

x = A(2:end,1);     % don't include origin; no data point available
y = A(1,2:end);     % ditto
z = A(2:end,2:end) ; 
surf (x, y, z)

Thank you very much. I got the point. Your written code worked after I added transpose to it. So, everything is fine now :)

"Your written code worked after I added transpose "

My code works as written; I see you used the alternate for X and Y than I did...I thought I pulled that from your original posted code, too, but apparently not.
