Is Matlab fixed-point or floating-point?

Fixed-Point Data in MATLAB and Simulink

Apply fixed-point data types to data in Simulink models and to data in MATLAB^® code.

What is fixed-point in Matlab?

The precision of a fixed-point number is the difference between successive values representable by its data type and scaling, which is equal to the value of its least significant bit. The value of the least significant bit, and therefore the precision of the number, is determined by the number of fractional bits.

What is fixed-point filter?

Fixed-point filters are commonly used in digital signal processors where data storage and power consumption are key limiting factors. With the constraints you specify, DSP System Toolbox™ software allows you to design efficient fixed-point filters. The filter for this example is a lowpass equiripple FIR filter.

What is IIR filter in Matlab?

Description. The IIR Filter block implements a discrete first-order infinite impulse response (IIR) filter on the specified input signal. The block supports fixed-point and floating-point data types.
