Write a matlab program, for a given fixed point equation, x=g(x), runs the fixed point algorithm xnew = g(xold) until either two consecutive approximation to the root are close enough (tolerance 10^-10), or divergence is determined. ...

In a recent survey conducted by AccelChip Inc. (recently acquired by Xilinx), 53% of the respondents identified floating- to fixed-point conversion as the most difficult aspect of implementing an algorithm on an FPGA (Figure 1).Tom Hill, XilinxEetimes Com...
“MATLAB, MATLAB Coder, and Fixed-Point Designer enabled our small team to develop a complex real-time signal processing algorithm, optimize it to reduce power and memory requirements, accelerate embedded code implementation, and perform the rigorous testing required for medical device validation.” ...
Although fixed-point context-sensitive constants can appear in expressions with any data types (including integers and floating-point data), their main use is with fixed-point numbers. The algorithm that interprets the context-sensitive constant computes a type that provides maximum accuracy without ...
If you are new to fixed-point modeling and you are looking for a direct path from floating-point MATLAB to fixed-point MATLAB code, use the automated workflow. Using this automated workflow, you can obtain data type proposals based on simulation ranges, static ranges, or both. For more info...
This example shows how to convert a MATLAB®algorithm containing structures to fixed point using the Fixed-Point Converter app. In a local writable folder, create the functionsstruct_fcn.m function[out, y] = struct_fcn(in)% create a nested structz = struct('prop1', struct('subprop1',...
This MATLAB function returns fixed-point types for A and B that guarantee no overflow will occur in the QR algorithm.

The goal of this paper is to propose an inexact fixed-point proximity algorithm to solve the [Math Processing Error]ℓ0-norm based regularization problem and prove its convergence to a local minimizer of the objective function without assuming the KL property. Specifically, we show that the pro...
