Fixed-Point Blockset

Accumulator

Compute a cumulative sum

Library

Calculus

Description

At time step n, the Accumulator block computes a cumulative sum of all input values u up to time n and outputs the sum.

Parameters and Dialog Box

Initial condition for previous output: Set the initial condition for the previous output.
Output data type and scaling: Specify the output data type and scaling via the dialog box, or inherit the data type and scaling from the driving block or by backpropagation.
Round toward: Rounding mode for the fixed-point output.
Saturate to max or min when overflows occur: If selected, fixed-point overflows saturate.
