Java matrix libraries

Question

I was wondering whether any of the well-known matrix libraries for Java, such as Colt or EJML, actually provide similar functionality as MatLab? For instance, I can\'t seem

Answer 1

The interface for COLT gives you a generic OP: assign(matrix, function), which you can use to add or subtract matrices and vectors.

As the javadocs for assign() says:

Assigns the result of a function to each cell; x[row,col] =function(x[row,col],y[row,col]).

So by using using an addition function as function - you can add matrices.
