How can I get the min/max value of all fields in a stucture

I would like to obtain the minimum and maximum value in my structure which contains multiple fields.

structure_1.field_01

structure_1.field_02

structure_1.field_03

structure_1.field_04

I require something like-

min_val = min(struct.(:));

Is this possible using one function?

thanks in advance,

Marcus

What is in field_01? Is it a scalar, a n-d double array, something else? How about field_02? Is it the same class and size as field_01?

Answer 1

[Andrei Bobrov]

out = min(structfun(@(x)min(x(:)),structure_1));

[Daniel Shub]

+1 for structfun, I just gave basically the same answer with cellfun, but structfun is much better.

Just what I was looking for. Thanks.

+1 too

Answer 2

Assuming the contents of the fields are well behaved ...

structure_1.field_01 = rand(1, 1);
structure_1.field_02 = rand(1, 10);
structure_1.field_03 = rand(10, 1);
structure_1.field_04 = rand(10, 10);
structure_1.field_05 = rand(10, 10, 10);
min(cellfun(@(x)min(structure_1.(x)(:)), fieldnames(structure_1)))

By well behaved I mean min(structure_1.field_01(:)) needs to return a scalar double.
