The magic Function
MATLAB actually has a built-in function that creates magic squares of almost any size.
Not surprisingly, this function is named magic. Read More

Manipulating Matrices
Matrices and Magic Squares
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. 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

elseif
elseif IF statement condition.
elseif is used with IF. The statements after the elseif are
executed if the expression is true and all the preceding IF and
elseif expressions are false. An expression is considered true if
the real part has all non-zero elements. Read More
end
end Terminate scope of FOR, WHILE, SWITCH, TRY, and IF statements. Without END’s, FOR, WHILE, SWITCH, TRY, and IF wait for further input. Each end is paired with the closest previous unpaired FOR, WHILE, SWITCH, TRY or IF and serves to terminate its scope. Read More
else
else Used with IF.
else is used with IF. The statements after the else are executed
if all the preceding IF and ELSEIF expressions are false. Read More
