B = repelem(A,r1,...,rN) returns an array with each element of A repeated according to r1,...,rN. Each r1,...,rN must either be a scalar or a vector with the same length as A in the corresponding dimension.
for index = values, statements, end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal.
B = repmat(A,n) returns an array containing n copies of A in the row and column dimensions. The size of B is size(A)*n when A is a matrix. example. B = repmat(A,r1,...,rN) specifies a list of scalars, r1,..,rN, that describes how copies of A are arranged in each dimension.
The result is, we can access each element in turn of a general n-d array using a single loop. For example, if we wanted to square the elements of A (yes, I know there are better ways to do this), one might do this:
18 paź 2023 · This improved version uses a for loop to repeat an operation—in this case, printing to the screen—once for each element in an array. The general form of a for loop is: for variable = collection do things with variable end {: .source} The for loop executes the commands in the loop body for every value in the array collection. This value is ...
To repeat a set of statements for each column of a matrix in MATLAB, you can use a for loop and access the columns using the colon operator : and the size function. Here’s an example: A = [1, 2, 3; 4, 5, 6]; for i = 1:size(A, 2) disp(A(:, i)) end
17 kwi 2016 · Use a “for” loop to calculate the elements o f the Fibonacci sequence for the maximum value in “N”. Then, use another “for” loop to display the values by indexing into the calculated sequence.
