• Matlab stores all types of variables as in the form of an array.
• A singlesingle elementelement arrayarray is called a scalarscalar.
• An arrayarray withwith oneone columncolumn oror rowrow is called a vectorvector.
•• AnAn arrayarray withwith mm rowsrows andand nn columnscolumns, where m,m, nn ≠≠ 11 is called amatrixmatrix.

• 3 way to determine ARRAYS in MatLAB:
x = start : increment : end
x = linspace (start, end, size of vector)
logspace
X = [a11, a12, a13 ;; a21, a22, a23]
x = x’’ (transpose of x)
