()-indexing must appear last in an index expression.

Do you know what is wrong with my indexing below? In my previous computer, I didn't have any problems. Thank you.

function [ wsys, wque ] = dowelch(cli, lambda, rep, win)
if nargin < 1 cli=3000; end
if nargin < 2 lambda = 90; end
if nargin < 3 rep=10; end
if nargin < 4 win=500; end
[ tsys, tque ] = mm1rep(cli, lambda, rep);
wsys = welch( mean(tsys)(:), win );
wque = welch( mean(tque)(:), win ); 
plot (wsys);

You can't daisy-chain indexing onto the end of a function return variable. E.g., this

wsys = welch( mean(tsys)(:), win );
wque = welch( mean(tque)(:), win );

needs to be something like this:

wsys = welch( reshape(mean(tsys),[],1), win );
wque = welch( reshape(mean(tque),[],1), win );

or this:

temp = mean(tsys);
wsys = welch( temp(:), win );
temp = mean(tque);
wque = welch( temp(:), win );
