Hi,
I have a matrix size data and i need to draw the plot.
%%%%%%%%%%%%%%%%%%%%%%
y1 y2 y3 y4
x1 a11 a12 a13 a14
x2 a21 a22 a23 a24
x3 a31 a32 a33 a34
%%%%%%%%%%%%%%%%%%%
when i try :
plot(x, y, z);
it gives me following error message:
Error using plot3
Vectors must be the same length.
So, how can i draw the graph for the above discrete case with different size of length?.
Thanks.

You can use pcolor and surf. Read about them.
x = 1:3 ;
y = 1:4 ;
A = rand(4,3) ;
figure
pcolor(x,y,A)
figure
surf(x,y,A)
