Function Reference

This section contains reference pages for the Fixed-Point Blockset M-file functions. In most cases, you will not call these functions from the MATLAB command line. Instead, they are automatically called when you specify certain parameter values via block dialog boxes or via the Fixed-Point Blockset Interface tool.

Function	Description
autofixexp	Automatically change the scaling for each fixed- point block that does not have its scaling locked.
fixptbestexp	Determine the exponent that gives the best precision fixed-point representation of a value.
fixptbestprec	Determine the maximum precision available for the fixed-point representation of a value.
fixpt_convert	Convert Simulink models and subsystems to fixed-point equivalents.
fixpt_convert_prep	Prepare a Simulink model for more complete conversion to fixed point.
fixpt_restore_links	Restore links for fixed-point blocks.
float	Create a MATLAB structure describing a floating-point data type.
fpupdate	Update obsolete fixed-point blocks from previous Fixed-Point Blockset releases to current fixed-point blocks.
fxptdlg	Launch the Fixed-Point Blockset Interface tool.
sfix	Create a MATLAB structure describing a signed generalized fixed-point data type.
sfrac	Create a MATLAB structure describing a signed fractional data type.
showfixptsimranges	Display the logged maximum and minimum values from the last simulation.
sint	Create a MATLAB structure describing a signed integer data type.
ufix	Create a MATLAB structure describing an unsigned generalized fixed-point data type.
ufrac	Create a MATLAB structure describing an unsigned fractional data type.
uint	Create a MATLAB structure describing an unsigned integer data type.
