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.
There are a number of ways you could do this without loops. Most solutions involve expanding the vectors x and y into larger matrices of indices and would likely use one or more of the functions REPMAT, BSXFUN, or SUB2IND. A good tutorial for matrix indexing can be found here.
A matrix is a two-dimensional array of numbers. In MATLAB, you create a matrix by entering elements in each row as comma or space delimited numbers and using semicolons to mark the end of each row.
These techniques will help you efficiently create, concatenate, and expand matrices in MATLAB and Simulink. Create a matrix or construct one from other matrices.

Create a matrix A with elements 1, 2, 3 in the first row and elements 4, 5, 6 in the second row. Square brackets are used to create a matrix. The elements in a row may be separated either by blanks or commas. Rows may be separated either by semicolons or newlines.
In MATLAB, a matrix is a rectangular array of numbers. Special meaning is sometimes attached to 1-by-1 matrices, which are scalars, and to matrices with only one row or column, which are vectors.
This is a slightly tedious way of creating a matrix, but it illustrates the important point of accessing individual entries, and the array nature of Matlab’smatrices.
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.
