extract the smallest value out of a strucuture in matlab

To extract the smallest value out of a MATLAB structure, you can use the built-in function struct2array to convert the structure to an array. Then, you can use the min function to get the smallest value.

For example, consider a structure S with fields a, b, and c:

main.m
S.a = 10;
S.b = 5;
S.c = 2;
28 chars
4 lines

To get the smallest value out of the structure, you can do:

main.m
A = struct2array(S);
min_val = min(A);
39 chars
3 lines

The variable min_val will contain the value 2, which is the smallest value in the structure.

Note that this approach assumes that all fields of the structure contain scalar numerical values. If your structure contains non-scalar values (such as arrays or cell arrays), you may need to modify the code accordingly to extract the values you want.
