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

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

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

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