I've generated these from rand(5,5)
0.1556 0.2725 0.0095 0.3996 0.8905
0.0614 0.7758 0.8284 0.2179 0.1670
0.6611 0.3314 0.9085 0.8816 0.4252
0.0186 0.6031 0.7053 0.9421 0.3269
0.2911 0.1840 0.2433 0.9490 0.5676
and I would like to check if each one of them are greater than
x = [0.01 0.01 0.01 0.01 0.02]
and I should get something like this:
1 1 0 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1

The algorithm can be as of:
Intialize a matrix with zeros to save your final result. Initialize another matrix to save your "x"
Try using a for loop to scan the rows and colums and use an if loop to compare the corresponding values and set the final result in the zero matrix.

It looks to me as if you want a 1 output if the matrix entries are greater than any one of the x values. If so you can compare to min(x) and not bother comparing to the other entries.

Here is an example using gt (greather than) and bsxfun :
A = repmat(1:5,5,1)
B = 5:-1:1
res = bsxfun(@gt,A,B)
where A is your rand matrix and B is your vector to compare with.
