%this script will find the minimum of a function/equation
clc
clear
%set variable equal to equation
t=-10:10;
%write for loop to loop our t values through our equation
for t=-10:10
%equation
y=3.*t.^2+2.*t+40;
%test to see if the next value in the loop is bigger than the last
if abs(y(t))>abs(y(t-1))
%if it is print result to command window
fprintf('The minimum value occurs at t=%0.3f',(t-1))
end
end
%this above is my script, whenever i run it i get this error
% "Array indices must be positive integers or logical values.
%Error in Lab5Script3 (line 9)
%if abs(y(t))>abs(y(t-1))"
%is there any ideas you could give me to help solve this error?

Define 'y' as an anonymous function:
y = @(t) 3.*t.^2+2.*t+40;
There are still a few problems. I will let you sort those.
