Array indicates must be positive integers or logical values

h=input('Number of subinterval: ');

sum=0;

for i=1:1:h-1

y(i)=input('List of numbers: ');

sum=sum+y(i);

end

answer=h/2+(y(0)+y(h)+2*sum);

disp(double(answer));

When I list my numbers in the y(i), the maximum number that I can type is 7 and then it shows the error "Array indicates must be positive integers or logical values". Anyone know how to fix this please help me

Hi,

Matlab Array indices start from 1.

Since you are using taking h as input and runnng loop till h-1 so both of following doesn't contains any value

y(0) and y(h)

As indices starts from 1 so h(0) isn't a valid input and you have taken input till h-1 so y(h) dosen't has any value.

Hence, you get error: Array indices must be positive integers or logical values.
