I am thinking of writing the data to a file. Does anyone have an example of how to write a big amount of data to a file? edit 1: Most elements in the matrix are zeroes, others are uint32. I guess the simplest save() and load() would work, as @Jonas suggested. ...

I am drawing a simple bar diagram in MATLAB. The problem is, that the value at x = 0 lets the y-axis disappear partially. Is there a way to bring the y-axis to the front instead of hiding between the y-value for x=0? Is there any option I can make sure the y-axis is always in the front? ...
Hello, I would like to know what is the use of having inputs in brackets like this : [fx, fxx] = differentiate(...) why is fx and fxx in square brackets ? Another example includes this [y,t,ysd] = step(m) Please explain ! Thanks ...
I have an object-oriented MATLAB app that needs a GUI, and I'd like to use GUIDE for the layout (at least). I've tried the manual way, and doing the control positioning is just too painful. I've noticed that GUIDE is very much procedurally-oriented; it generates M-files that assume they are run from the path and aren't associated with a...

I want to compute a diffusion kernel, which involves taking exp(b*A) where A is a large matrix. In order to play with values of b, I'd like to diagonalize A (so that exp(A) runs quickly). My matrix is about 25k x 25k, but is very sparse - only about 60k values are non-zero. Matlab's "eigs" function runs of out memory, as does octave's ...
I have a MATLAB function that I've compiled into a .net library. The function is a simple one that takes a character array as an input and a numeric array as output: function insert = money(dateLimit) .. insert = [1 2]; The function works fine when no function arguments are specified (a default argument is provided inside the function)...

I have a set of code that, depending on how the program is initiated, will either be executed locally or sent to a remote machine for execution. The ideal way I imagine this could work would look something like the following: line_of_code = 'do_something_or_other();'; if execute_remotely send_via_udp(line_of_code); else eval(li...
