Dot indexing is not supported for variables of this type.

When I run the following commands in MATPOWER,

clear;

clc;

result=runpf(case14)

bus=result.bus(:,8)

I am getting an error message as:

... result =

100

Dot indexing is not supported for variables of this type.

Error in loadflow (line 4)

bus=result.bus(:,8).

Kindly provide your valuable suggestions.
