function [m,s] = inputtrial(x)
n = length(x);
m = avg(x,n);
s = sqrt(sum((x-m).^2/n));
end
function m = avg(x,n)
m = sum(x)/n;
end
values[] = [12.7, 45.4, 98.9, 26.6, 53.1];
[ave,stdev] = inputtrial(values)

In MATLAB, you can define an array like this
values = [12.7, 45.4, 98.9, 26.6, 53.1];
% values[] is a syntax error

I've tried it also, but still showing error
function [m,s] = inputtrial(x)
n = length(x);
m = avg(x,n);
s = sqrt(sum((x-m).^2/n));
end
function m = avg(x,n)
m = sum(x)/n;
end
values = [12.7, 45.4, 98.9, 26.6, 53.1];
[ave,stdev] = inputtrial(values)
Error: File: inputtrial.m Line: 11 Column: 3
This statement is not inside any function.
(It follows the END that terminates the definition of the function "avg".)

In MATLAB, the lines of code must precede the function definitions. So move the last two lines to the top
values = [12.7, 45.4, 98.9, 26.6, 53.1];
[ave,stdev] = inputtrial(values)
function [m,s] = inputtrial(x)
n = length(x);
m = avg(x,n);
s = sqrt(sum((x-m).^2/n));
end
function m = avg(x,n)
m = sum(x)/n;
end
