Find Array Elements That Meet Conditions. This example shows how to filter the elements of an array by applying conditions to the array. For instance, you can examine the even elements in a matrix, find the location of all 0s in a multidimensional array, or replace NaN values in data.

- Find
k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. example.
MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the zeros and ones functions create matrices of all zeros or all ones. The first and second arguments of these functions are the number of rows and number of columns of the matrix, respectively.
16 sty 2013 · Perhaps you could try creating a 6x6 matrix full of zeros: M = zeros(6) Then just setting part of it to 1:9? M(4:6,4:6) = reshape(1:9, 3, 3)' (The ' symbol means transpose)
1 paź 2021 · Accepted Answer: DGM. Hi, I have a matrix (6x21) whose values are those found experimentally. Let's call it: expbasket. I want to calculate the error between the obtained matrix and a matrix having real values. The real values are in row order: -9; -6; -3; 3; 6; 9 and every columns it's the same. So I have to have a matrix like this:

18 lis 2013 · how to select specific values in a matrix. Hi I will give an example, I have a 10X10 matrix, I want to select the 4th value in the first row, the 7th value in the 4th row and value 5 onwards on the 3rd row, and selecting multiple values from different rows. If anyone can help me. Thanks.
