logic question regarding two vectors
显示 更早的评论
The two vectors, x=[0, -4, 7, 0, -1, 2], y=[1, -4, 8, 0, 1, 6] are given. Explain how matlab could reutrn...z = x and (not y)

Really have no idea what you are asking.... just guessing
x=[0, -4, 7, 0, -1, 2];
y=[1, -4, 8, 0, 1, 6];
z=min(x,y)

im not understanding this HW question ...
x=[0, -4, 7, 0, -1, 2];
y=[1, -4, 8, 0, 1, 6];
z=x&~y
z=(x&y)|(~x)
Note, x and y vectors can be converted to logical vectors: anynumbers not zero are logical 1, otherwise logical zero
logical(x)
logical(y)

This was obviously a homework question though...

We discourage volunteers from giving complete code for homework questions, as we find that when we do that, often the people do not learn the techniques, and instead mostly copy the answer given. We encourage the volunteers to instead answer in ways that teach the concepts, leaving the people asking the questions to apply the concepts to arrive at the answer.

The "or" operation for vectors is written as the | operator.
The "and" operation for vectors is written as the & operator.
The "not" operation for vectors is written as the ~ operator.
Note that for the purpose of MATLAB, a value is considered true if it is non-zero (except that it is an error to apply logical tests directly to NaN values.)
