M_matrix -- a small embeddable one-line language based on the old LA matlab(3f) routine

[urbanjost]

M_matrix started as a homage to the old matlab88(3f) program but by extending it to interact easily with Fortran programs it is evolving into a useful tool for everything from inspecting data during development to providing a programmable configuration file format to supporting the creation of quick unit tests with the option to interactively dive on the results of the tests. I have been seeing a significant amount of downloads even though it is nowhere near being mature, and it is useful enough in it's current state that you might want to take a look. As time permits I will add some more graphics interfaces to allow for basic visualization capabilitites and am hoping to make it far easier using procedure pointers to easily build interfaces to other fpm packages. some basic statistics will come shortly. Among other things, if you have a vector or 2-D matrix of data in your program and want to interactively examine the data, save it to a file or compare it to values from a previous run and so on you can add two or three lines to your program and you are good to go.
