How to extract some values from a structure?
3 views (last 30 days)
I have a structure A which has several fields. Each field has 100 values. I want to extract the first 20 values from each field and save them in a structure B. I tried to use the following code:
B = A(1:20).
It does not work. Would you please tell me how I can get structure B?

Assuming that structure A is scalar (so far you did not tell us this important information):
A.x = randi(9,1,100);
A.y = randi(9,1,100);
A.z = randi(9,1,100)
fun = @(v)v(1:20);
B = structfun(fun,A,'uni',0)
