i have a few structures i want to save in mat file. eg
s(1).a = 'hello'; s(1).b = 99; s(2).a = 'bye'; s(3).b = 82;
i want to save structure s(1) and s(2) into a mat file. i did this, save('test_struct.mat',marker(1)); but it give me error, Argument must contain a string.

@genesis: And now you have seen David's answer, which explains, that you need the string 's' instead of the variable s(1). If this solves your problem, please accept his answer.

When using save, the name of the variable to be saved has to be a string:
s.name='ww';
s.age=22;
save('test.mat','s')
For structs, try the following, copied from matlab documentation:
Save the fields of structure s1 as individual variables. Check the contents of the file with the whos function. Clear the workspace and load the contents of a single field.
s1.a = 12.7;
s1.b = {'abc', [4 5; 6 7]};
s1.c = 'Hello!';
save('newstruct.mat', '-struct', 's1');
disp('Contents of newstruct.mat:')
whos('-file', 'newstruct.mat')
clear('s1')
load('newstruct.mat', 'b')
