A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, categorical values, or some other MATLAB data type. Even a single number is stored as a matrix.
https://www.mathworks.com/matlabcentral/answers/383970-how-can-i-combine-two-matrices. Commented: Matt J on 21 Feb 2018. Accepted Answer: Birdman. A = [1 2 3; 4 5 6; 7 8 9] B = [10 11 12; 13 14 15] C = [1 2 3; 4 5 6; 7 8 9; 10 11 12; 13 14 15]
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].
A 2-by-2 matrix is an array of four numbers arranged in two rows and two columns. A = (a1;1 a1;2 a2;1 a2;2) or A = (a1;1 a1;2; a2;1 a2;2) For example A = (4 3 2 1)-10 -8 -6 -4 -2 0 2 4 6 8 10-10-8-6-4-2 0 2 4 6 8 10 x Ax Figure 4.1.

Matrices are an effective way to modify an entire set of numbers in one operation. Simple ways to modify matrices include addition, subtraction, multiplication, and division by a scalar, or individual number. When completing these operations, complete the calculation with each number in the matrix, as denoted below.
We can define a matrix by columns instead of rows by switching the position of the colon: b(:,1) = [1 2 3 4]’ b(:,2) = [5 6 7 8]’. note the apostrophe after the bracket – without this apostrophe, we would be telling Matlab to assign a row of numbers to a column, which Matlab can’t make any sense of.
