This MATLAB function returns an array Y the same size as x, where each element of Y is: 1 if the corresponding element of x is greater than 0.

For real inputs, theSignblock outputs the sign of the input: InputOutput Greater than zero1 Equal to zero0 Less than zero–1 When the inputuis a complex scalar, the block output matches the MATLAB®result for: sign(u) = u./ abs(u)(1) ...
번역 I have a matrix like n=[x,y,z] I need to consider plus and minus sign of x,y and z "at the same time" because I need unique permutation of mix signs as well s.t. [-x,y,z],[x,-y,-z],etc. 댓글 수: 0 ...
% I am asked to find the maximum (using built-in MATLAB functions) of each % of columns 2,3 and 4, then determine the time of each of these maximums. % How would I go about doing this?\ % I know that [M,I]=max(A)% gives me max of each column and indexes the row but ho...
How to create a (nxn) matrix with alternating signHow do i create a (n x n) matrix whose elements are either +3 or –3 such that the sign of each element is different from its adjacent elements, both from those above and below it and from those on either side of it (see Y ...
I not using Matlab. But I can say this also happens in Julia, if the matrix is complex. For real numbers it doesn't, because it's a different algorithm. For an actually complex matrix (e.g, [0,1i;1,0]) we can even get a phase change, not just a sign change. ...
How to find multliple values in larger arrays where the value two below is the opposite sign (+ve/-ve)to get the sign of the matrix, and compare them with an offset of 2 on the rows:編
