**randomly select elements of an array MATLAB Answers**

The reason is the full matrix is very large and the majority of elements are zeros. It takes a big portion of my computer memory (greater than 8 GB of my RAM capacity). The above matrix is only a small sample of my problem. Note that for this problem, the nonzero elements are located in the diagonal of the matrix.... I have a matrix A. From it, I want to choose only some of the specific elements and place them in another array B at the specified locations. But, by default it is becoming of the same dimension as A, with zero at those locations.

I have an NxN matrix and define a circle of a certain radius. All encircled matrix elements are 1 and the rest 0. Afterwards, I want to apply some multiplication only for the 1s.... 2) duplicate every non-zero element from this row with a some probability and add it to the matrix. 3) enlarge the size of the matrix (to keep it square) 4) repeate the procedure with the new matrix (with added row), say, 10 times.

**randomly select elements of an array MATLAB Answers**

If A is a vector, then all(A) returns logical 1 (true) if all the elements are nonzero and returns logical 0 (false) if one or more elements are zero. If A is a nonempty matrix, then all(A) treats the columns of A as vectors and returns a row vector of logical 1 s and 0 s. how to make clear putty without borax If A is a vector, then all(A) returns logical 1 (true) if all the elements are nonzero and returns logical 0 (false) if one or more elements are zero. If A is a nonempty matrix, then all(A) treats the columns of A as vectors and returns a row vector of logical 1 s and 0 s.

- In MATLAB notation, the j-kth element of an array named A is denoted A(j,k). In the example above, the same element is identified as A(2,3) . When dealing with and using arrays, it is vital to keep the values of the elements distinct from the indices used to locate them.
- 4/06/2007 · Subject: [matlab] how can we select a random element of a matrix Hi all, How can we select random elements from a matrix. Let suppose, we have a 3x4 matrix, 2 4 6 3 6 8 4 2 2 5 6 7 we want to randomly select 3 elements form that matrix, it doesn't matter from which column or row. What matlab code should we write? Thank you, ***** This email and any files transmitted with it are …
- I want to compare these arrays and put the result in another array of same size,such that during comparison if the compared elements have the same sign (-/- or +/+) then the new resulted array should get NaN for that comparison entry and if the signs of the compared elements is different(-/+ or +/-), then keep the original value of the original
