I'm working with a script that calls a function several times (about 1000); in this function, a large complex-valued matrix is used, this matrix called "promat" is saved in file also named "promat.mat". To be specific, my function is following:
function y=process(x)do something with xy=x.*promat;end
I think about three solutions:
+ First: load promat to work space, then set it as global variable and declare it in the function.
+ Second: load promat to work space, then set it as an input of the function as:
+ Third: load the matrix inside the function.
I wonder what is the fastest and most efficient way to do it, both in memory use efficiency and performance. Any answers and discusses will be appreciated :).
