Jitter Matrix Output

When using jitter matrices, it's possible to set values for various areas of a 2 dimensional matrix using the message setcell $2 $3 value $1 and whatever numbers you want. What would be the corresponding message to do the opposite, namely to take the numerical data from a matrix in the form of cells and values and output it? It's possible to do this using jit.print and send it into the Max window, but how do I get it into a patcher? Does this question make sense? If so, any help or ideas? Cheers, thanks. Stoopchow
