accessing data from a struct
显示 更早的评论
I have R, which is a 1x1 struct, which contains a matrix named X. I want to access X, how do I this? I want to load X into the workgroup.
R(1) doesn't seem to do it.

How to access data in structures is explained in the MATLAB documentation:

Hi,
A = R.X
assigns the Matrix saved in the field X of the struct R to A.
% define empty struct
R = struct()
% add field X containing a matrix
R.X = [1 2 3; 4 5 6]
% assign the matrix from field X to new variable A
A = R.X
% get one element from field x and assign to a
a = R.X(2,3)
Best regards
Stephan

How then do you open a .mat file which is a struct?
"How then do you open a .mat file which is a struct?"
A MAT-file is not a structure, a MAT-file is a container which can hold many variables of many classes. It is certainly possible that one or more of those variables are structures (but that does not mean that the file itself "is" a structure).
MAT-files are never/rarely opened, they are simply LOADed:
S = load(nameofthematfile)
