subarrays. Suppose X is an ordinary matrix and L is a matrix of the same size that is the
result of some logical operation. Then X(L) specifies the elements of X where the
elements of L are nonzero. Read More

More precisely, a
matrix is a two-dimensional numeric array that represents a linear transformation. The
mathematical operations defined on matrices are the subject of linear algebra. Read More

The format function controls the numeric format of the values displayed. The function affects only how numbers are displayed, not how MATLAB software computes or saves them. Here are the different formats, together with the resulting output produced from a vector x with components of different magnitudes. Read More

Matlab MatrisIn 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. MATLAB has other ways of storing both numeric and nonnumeric data, but in the beginning, it is usually best to think of everything as a matrix. The operations in MATLAB are designed to be as natural as possible. Where other programming languages work with numbers one at a time, MATLAB allows you to work with entire matrices quickly and easily. A good example matrix, used throughout this book, appears in the Renaissance engraving Melancholia I by the German artist and amateur mathematician Albrecht Dürer. Read More
