Syntax

I = Integral(x,y)

Argument

Name

Description

x

A vector of the independent variable values.

y

A vector of the dependent variable values at the independent variable values. Must be of same length as x.

Output

Name

Description

I

The integral up to at each point of x.

Example

Find the integral up to each point of x:

Syntax

x = [1:5]

y = Exp(x)

I = Integral(x,y)

Result

I = 0  5.0537  18.791  56.133  157.64

Comments

The algorithm uses the trapezoidal method.  The argument values must be real.
