Plotting image with position

Hello,

There's been a long time since I didn't use matlab and
I've forgotten which function to use if I want to plot an
image with followong properties :

C is a 1 by 100 vector containing intensity
X is a 1 by 100 vector containing positions along x
Y is a 1 by 100 vector containing positions along y

Note : X and Y are not ranged by increasing positions

image and imagesc seem not to be fitted for such
application ... ?

Thanks a lot

Flav
