如何在Matlab中获得矢量的一部分

Question

I want to get parts of a vector V with width W As a result, I want to get M = N*M , so that if I say M(2,:) , I will get all the values of V(2*W : 3*W) .

Any Ideas?

Not entirely sure what you mean, but does

M = reshape(V, W,[]);

come close? Otherwise, try

M = reshape(V, W,[]).';

or

M = reshape(V, [],W);
