FixPt Look-Up Table Vector of output values The vector of output values must be the same size as the input vector. Look-up method Look-up method. Output data type and scaling Specify the output data type and scaling via the dialog box, or inherit the data type and scaling by back propagation. Output data type Any data type supported by the Fixed-Point Blockset. Output scaling Radix point-only or slope/bias scaling. These scaling modes are available only for generalized fixed-point data types. Lock output scaling so autoscaling tool can’t change it If checked, Output scaling is locked. This feature is available only for generalized fixed-point output. Round toward Rounding mode for the fixed-point output. Saturate to max or min when overflows occur If checked, fixed-point overflows saturate. Otherwise, they wrap. Override data type(s) with doubles If checked, the Output data type is overridden with doubles. Log minimums and maximums If checked, minimum and maximum simulation values are logged to the workspace. Conversions 9-68 The Vector of input values parameter is converted from doubles to the input data type. The Vector of output values parameter is converted from doubles to the output data type. Both conversion are performed offline using round-to-nearest and saturation. Refer to “Parameter Conversions” on page 4-26 for more information about parameter conversions.
