How do you use nonzeros in MATLAB?
View MATLAB Command Use nonzeros to return the nonzero elements in a sparse matrix. Create a 10-by-10 sparse matrix that contains a few nonzero elements. The typical display of sparse matrices shows a list of the nonzero values and their locations.
How do you find the nonzero values in a matrix?
Use nonzeros, nnz, and find to locate and count nonzero matrix elements. Create a 10-by-10 random sparse matrix with 7% density of nonzeros. A = sprand(10,10,0.07); Use nonzeros to find the values of the nonzero elements.
What is the difference between a vector and a nonempty matrix?
If A is a vector, then B = any (A) returns logical 1 ( true ) if any of the elements of A is a nonzero number or is logical 1, and returns logical 0 ( false ) if all the elements are zero. If A is a nonempty, nonvector matrix, then B = any (A) treats the columns of A as vectors, returning a row vector of logical 1 s and 0 s.
What is the nonzero element in the column vector?
Nonzero elements, returned as a column vector. v is returned in full-storage regardless of whether A is full or sparse. The elements in v are ordered first by column subscript and then by row subscript. nonzeros gives the v, but not the indices i and j, from [i,j,v] = find (A) .
What is nrnrzi (non-return to zero inverted encoding)?
NRZI [Non-Return-to-Zero-Inverted Encoding]: A ‘0’ is encoded as no change in the level. However a ‘1’ is encoded depending on the current state of the line. If the current state is ‘0’ [low] the ‘1’ will be encoded as a high, if the current state is ‘1’ [high] the ‘1’ will be encoded as a low.
What is the encoding scheme for non return to zero?
If the significant condition transition occurs on each one, the encoding scheme is called non-return to zero mark (NRZ-M). NRZI [Non-Return-to-Zero-Inverted Encoding]: A ‘0’ is encoded as no change in the level. However a ‘1’ is encoded depending on the current state of the line.
