Hey guys, I need help with an integral using variable bounds.
I Have a certain function:
f = @(t) [function]
And I want to Integrate this function with respect to t, so:
Nf = integral(f,x,y)
However, x and y are variables:
i = 1:35040
x = (1/(24*4))*(i-1)
y = (1/(24*4))*i
I want to store the results of these integration in a matrix:
M = [Nf(1), NF(2), .., NF(35040)]
A loop function does not seem to work:
for i=1:35040
f = @(t) [function]
x = (1/(24*4))*(i-1)
y = (1/(24*4))*i
Nf = integral(f,x,y)
end

请先登录，再回答此问题。

syms x y %example
f = @(t) sin(t)
Nf = int(f,x,y)
i = 1:35040;
x = (1/(24*4))*(i-1);
y = (1/(24*4))*i;
result=vpa(subs(Nf),2)
