using pcolor to plot 2d array with different cell size in matlab

Question

i have a domain of interest and this domain will be converted onto finite difference grid with cells (rows,columns)
a 2-D array (cond) contains the conductivity values assigned to each cell in the desired domain
when i use the pcolor command in matlab

pcolor(cond); shading flat

the output figure consider every cell as 1mx1m
if the actual cell differs than 1m (2m, 5m, etc.)
how could i plot using pcolor but each cell will be displayed as it's actual size

You can specify the axis with pcolor by putting x and y as first arguments:

x = 1:2:10;
y = 1:5:51;
pcolor (x, y, cond);
