matlab - boolean 值和逻辑值之间的区别

Question

出于好奇，如果我在 MATLAB 中输入这些行:

a = logical([12 0 1.2]);
b = boolean([12 0 1.2]);

输出变量a 和b 是相同的(相同的值和类型)。因此，boolean 和 logical 之间有什么区别吗？

Answer 1

快速浏览一下 boolean 函数可以很好地回答您的问题:

如果您在 matlab 控制台中键入:edit boolean，您将获得:

function y = boolean(x)
%BOOLEAN Creates a boolean vector.
%   This function is typically used in Simulink parameter dialogs, such as
%   the Constant block dialog.  This function generates a logical vector,
%   which is treated as a boolean value in Simulink.  Now that logical is a
%   MATLAB type, this function is essentially just an alias.
%
%   Y = BOOLEAN(X) Converts the vector X into a boolean vector.
%
%   Example: 
%      boolean([0 1 1]) returns [0 1 1]
%
%   See also LOGICAL.

narginchk(1,1);

if ~isreal(x)
    DAStudio.error('Simulink:utility:BooleanCannotBeComplex');
end

y = logical(x);

如果您查看此函数的最后一行，您会发现 boolean 函数调用了逻辑函数。
