For example, to round values in an array x to the nearest fifth, use roundfrac(x,1/5). Syntax Xrounded = roundfrac(X,fraction) Xrounded = roundfrac(X,fraction,option) Description Xrounded = roundfrac(X,fraction) rounds X to multiples of nearest fraction. If fraction is a scalar, ...
x = fi(2*rand(1000,1)-1,true,16,15); % Input signal a = fi(.9,true,16,15); % Feedback gain y = fi(zeros(size(x)),true,16,12); % Initialize output. Fraction length % is chosen to prevent overflow w = fi(0,true,16,12); % Initialize delayed output A = coder.Constant(...

由于matlab各版本部分语法存在差异,可能会出现bug,用help查帮助文档即可。 里面的一些内容仅供参考,知识量有限,仅供入门。 后期可能会随缘写一点笔记。 如果没有装Matlab,我这里有一篇建模软件的博客:https://www.cnblogs.com/cruelty_angel/p/10563509.html ...
