For example, find(X<5) returns the linear indices to the elements in X that are less than 5. To directly find the elements in X that satisfy the condition X<5, use X(X<5). Avoid function calls like X(find(X<5)), which unnecessarily use find on a logical matrix.

14 lut 2021 · Hi guys, I need to create a matrix (in my script is "array"), deriving from a function, depending on three variables, which alternate. clear all Var; %from which I derive T1 and m1 beta= 0.05; ...
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.
10 lut 2014 · You can't make a matrix of functions, but you can make cell of function handles, e.g. cellOfFunctions = {}; for i = 1:3. cellOfFunctions{end + 1} = @(y) y*i; end. Then you can get each handle as follows (for the first function handle): fh1 = cellOfFunctions{1}; Then execute it with y = 3: result = fh1(3);
7 gru 2014 · Now I have $-1=x_0<x_1 <...<x_n=1$ with $x_i=x_{i-1}+h$ and $h=2/n$. Now given a function $f$, I want to find $f(x_i)$ for $i=1:n-1$ and store it in a column matrix $F$. How will I code it in matlab?
MATLAB provides efficient functions to create some commonly used matrices. Create a 3 by 5 matrix with all elements equal to zero. The command zeros(m,n) creates an m by n array (matrix) of zeros.
14 lut 2024 · The find() function in MATLAB is used to locate the indices of non-zero elements in an array or matrix. It is a versatile function that can be applied to vectors, matrices, and multidimensional arrays. The syntax of the find() function is flexible, accommodating different scenarios: indices = find(X)
