如何将矩阵中的小数转换为整数? [英] How to convert decimals in a matrix to integers?

问题描述

如果我的输入矩阵是:

v =

       -0.7071    0.5774    0.4082
        0.0000   -0.5774    0.8165
        0.7071    0.5774    0.4082

输出应为:

v =
       -1         1         1
        0        -1         2
        1         1         1

推荐答案

[A,B] = size(v)
for ii = 1:B
    v(:,ii) = v(:,ii)./abs(min(v(:,ii)));
end

如果这是您的确切例子.

In case this is the exact example you have.

以防万一，双打不够好:

And just in case doubles are not good enough:

v = int32(v); % or whichever integer you want

bsxfun方式，感谢@rayryeng:

bsxfun way, thanks to @rayryeng:

v = bsxfun(@rdivide, v, abs(min(v,1)));
