    Computes the mean square error (mse) of two sequences.

    connector_pane_image
    datatype_icon

    y

    Array of values.

    If the number of elements in y is different from the number of elements in x, the node computes mse based on the sequence that contains the fewest elements and returns a warning.

    datatype_icon

    x

    Array of values.

    If the number of elements in x is different from the number of elements in y, the node computes mse based on the sequence that contains the fewest elements and returns a warning.

    datatype_icon

    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error

    datatype_icon

    mse

    Mean square error.

    If one of the input sequences is an empty array, the value of mse is NaN.

    datatype_icon

    error out

    Error information. The node produces this output according to standard error behavior.

    Algorithm for Computing the MSE

    The node calculates mse using the following equation.

    mse = 1 n i = 0 n 1 ( x i y i ) 2

    where

    • n is the number of data points
    • xi is the ith element of x
    • yi is the ith element of y

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
