I have several mat structures and i just want to combine all of them into one ginourmous mat structure.

Add a structure to a mat file in matlab.

Access specific parts of a variable in a mat file using the mat file object. Sorry for asking for more but would it be difficult to modify the script to work in suituation where mat fail contains two variables each with two columns so the in the result instead of one merged mat file there would be two mat files first containing first variables and second containing second variables.

For example you can save data to a subset of a variable in a mat file or read a subset of a variable into the matlab workspace.

These variables can be returned to the workspace using load. If you do not specify filename the load function searches for a file named matlab mat.
