The simplest way is to load your variable into a structure, simply by giving an output to load, then you can use dynamic field names to access your variables:
matcontent = load Test_2_4_1.mat;
usefield = strncmpi(fieldnames(matcontent),'PEC',3);
%instead of a loop you can then convert the structure into a cell array and simply index the cell array:
matcontent = struct2cell(matcontent);
selectedvariables = matcontent(usefield); %cell array of selected variables
Note:
- do not use ans as a variable name. This is a name reserved by matlab. The content of ans can change at any time (any time you don't provide an output to a function).
- avoid eval, evalin, etc. like the plague.
- if x == 1 when x is logical (as in your case) is the same as if x. Converting x to double and then comparing to 1 is a complete waste of time.
