Performs the discrete integration of the sampled signal.
Sampled signal from time 0 to n1, where n is the number of elements in the sampled signal.
This input accepts a doubleprecision, floatingpoint number or a 1D array of doubleprecision, floatingpoint numbers.
Method to use to perform the numeric integration.
Name  Value  Description 

Trapezoidal Rule  0 
Uses the trapezoidal rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = d t, then
${\int}_{{t}_{0}}^{{t}_{1}}x\left(t\right)dt\approx \frac{dt}{2}\left(x\right({t}_{0})+x({t}_{1}\left)\right)$

Simpson's Rule  1 
Uses the Simpson's rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = t _{2}  t _{1} = d t, then
${\int}_{{t}_{0}}^{{t}_{2}}x\left(t\right)dt\approx \frac{dt}{3}\left(x\right({t}_{0})+4x({t}_{1})+x({t}_{2}\left)\right)$

Simpson's 3/8 Rule  2 
Uses the Simpson's 3/8 rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = t _{2}  t _{1} = t _{3}  t _{2} = d t, then
${\int}_{{t}_{0}}^{{t}_{3}}x\left(t\right)dt\approx \frac{3dt}{8}\left(x\right({t}_{0})+3x({t}_{1})+3x({t}_{2})+x({t}_{3}\left)\right)$

Boole's Rule  3 
Uses the Boole's rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = t _{2}  t _{1} = t _{3}  t _{2} = t _{4}  t _{3} = d t, then
${\int}_{{t}_{0}}^{{t}_{4}}x\left(t\right)dt\approx \frac{2dt}{45}\left(7x\right({t}_{0})+32x({t}_{1})+12x({t}_{2})+32x({t}_{3})+7x({t}_{4}\left)\right)$

Forward Euler  4  Uses the forward Euler rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = d t, then
${\int}_{{t}_{0}}^{{t}_{1}}x\left(t\right)dt\approx dt\cdot x\left({t}_{0}\right)$

Backward Euler  5  Uses the backward Euler rule defined by the following equation:
Let x(t) be a function of t and t _{1}  t _{0} = d t, then
${\int}_{{t}_{0}}^{{t}_{1}}x\left(t\right)dt\approx dt\cdot x\left({t}_{1}\right)$

Default: Simpson's Rule
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Sampling interval.
Default: 1
Discrete integration of the sampled signal.
This output can return a doubleprecision, floatingpoint number or a 1D array of doubleprecision, floatingpoint numbers.
Error information.
