I have a 451x250 double in my workspace, I would like to used it as a look-up talbe in simulink with the indicies as reference, so that array(1,1) would give the first number as output. How can this be done ?

Have you tried the n-d lookup tables? If that doesn't work you can also try defining it as a data store. You can setup the IC of the data store as this matrix then use a data store read along with a selector block that allows for a lot of flexibility.

I have tried the n-d lookup table, but when I try to import the matrix from the workspace or from file, I get a 1d vector.

I dont get the idea of using the data store block ?

Dennis: You don't need to import the matrix as a signal using the From Workspace/File block, simply enter the name of the variable in the 'Table data' field of the n-D Lookup Table's dialog window.
