Square bracket operator []
- You can use the square bracket operator [] to concatenate or append arrays. For example, [A,B] and [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically.

I'm currently trying to make a 7x2 matrix and a 3x2 matrix into one 10x2 matrix. what I'd like to do is just "stack" the 2 on top of each other. is there any easy way to do this? thanks.

Create a cell array containing two matrices, and concatenate the matrices both vertically and horizontally. M1 = [1 2; 3 4]; M2 = [5 6; 7 8]; A1 = {M1,M2}; Cvert = cat(1,A1{:}) Cvert = 4×2 1 2 3 4 5 6 7 8

If you have a specific set of data, you can arrange the elements in a matrix using square brackets. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements. The size of the resulting matrix is 1-by-4 because it has one row and four columns. A ma...
MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the zeros and onesfunctions 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. The diag function places the input elements ...
You can also use square brackets to append existing matrices. This way of creating a matrix is called concatenation. For example, concatenate two row vectors to make an even longer row vector. To arrange A and Bas two rows of a matrix, use the semicolon. To concatenate several matrices, they must have compatible sizes. In other words, when you conc...
The colonis a handy way to create matrices whose elements are sequential and evenly spaced. For example, create a row vector whose elements are the integers from 1 to 10. You can use the colon operator to create a sequence of numbers within any range, incremented by one. To change the value of the sequence increment, specify the increment value in ...
You can add one or more elements to a matrix by placing them outside of the existing row and column index boundaries. MATLAB automatically pads the matrix with zeros to keep it rectangular. For example, create a 2-by-3 matrix and add an additional row and column to it by inserting an element in the (3,4) position. You can also expand the size by in...
An empty array in MATLAB is an array with at least one dimension length equal to zero. Empty arrays are useful for representing the concept of "nothing" programmatically. For example, suppose you want to find all elements of a vector that are less than 0, but there are none. The findfunction returns an empty vector of indices, indicating that it di...
Jan 3, 2018 · How can I combine 2 matrices A, B into one so that the new matrix C = row 1 of A, followed by row 1 of B, then row 2 of A, row 2 of B, row 3 of A, row 3 of B, etc? Preferably without a for loop? ex: A = [1 2 3; 4 5 6], B = [5 5 5; 8 8 8].
Nov 13, 2023 · In MATLAB, concatenating matrices means combining two or more matrices together to create a single large matrix having elements of all the matrices. Concatenating matrices is an important operation when we need to combine data from multiple sources.
