Multiply structure by a constant

Like to multiply a structure with fields by a constant, but it giving an error. Is there another way to do this?

Answer 1

[Matt J]

s.a=1; s.b=2,

s = struct with fields:
    a: 1
    b: 2

S=structfun(@(f)10*f,s,'uni',0) %multiply by 10

S = struct with fields:
    a: 10
    b: 20

Answer 2

You have to cycle through the individual fields of the structure:

s = struct('a', [1 2 3 4], 'b', -1)

s = struct with fields:
    a: [1 2 3 4]
    b: -1

for f = fieldnames(s)'
    s.(f{1}) = 4 * s.(f{1});
end
s

s = struct with fields:
    a: [4 8 12 16]
    b: -4

It is mainly 1 by 1 value, do you still need to do this as i have variable names

[Bora Eryilmaz]

Not sure what you mean by "variable names". Are you referring to the variable name of the struct or the fields of the struct?
