在MATLAB中使用'rand'实现'randi' [英] Implement 'randi' using 'rand' in MATLAB

问题描述

为了增加向后兼容性，我想将所有"randi([m，n])"替换为仅使用rand的某个函数，因为使用较早版本的MATLAB的人没有randi函数.

To increase backward compatibility i want to replace all my "randi([m,n])" to some function that uses only rand, as people with earlier versions of MATLAB do not have randi function.

推荐答案

如果您在谈论randi(imax,[m,n])，则可以使用类似以下内容的东西:

If you're talking about randi(imax,[m,n]), you could use something like:

ceil(imax*rand([m,n]))

如果您的意思是randi([imin,imax])，请参阅注释中提供的Amro链接:

If you mean randi([imin,imax]), refer to the link Amro provided in the comments: Using rand in matlab to produce numbers between limits
