Hi...
Does Matlab allows to globalize matrix of elements using global function?
I have more than one function file and I want to put the constant values in matrices in one file and globalize it to the other files.
Thanks in advance

You can create a function for this:
function x = IC(i1, i2)
IC = [1.04 0 .716 .27 0 0; ...
1.025 9.3 1.63 0.067 0 0; ...
1.025 4.7 .85 -.109 0 0; ...
1.026 -2.2 0 0 0 0; ...
0.996 -4 0 0 1.25 .5; ...
1.013 -3.7 0 0 .9 .3; ...
1.026 3.7 0 0 0 0; ...
1.016 .7 0 0 1 .35; ...
1.032 2 0 0 0 0];
x = IC(i1, i2);
Now "IC(2,3)" replies the desired element.

Yes, it must be a separate file. The name of the function is IC. Excluding &nbsp ; ... &nbsp will save you some typing
function x = IC(i1,i2)
buf = [ .04 0 .716 .27 0 0
1.025 9.3 1.63 0.067 0 0
1.025 4.7 .85 -.109 0 0
1.026 -2.2 0 0 0 0
0.996 -4 0 0 1.25 .5
1.013 -3.7 0 0 .9 .3
1.026 3.7 0 0 0 0
1.016 .7 0 0 1 .35
1.032 2 0 0 0 0 ];
x = buf(i1,i2)
end
