Examples of valid names: Examples of invalid names: x6 6x lastValue end n_factorial n! Conflicts with Function Names Avoid creating variables with the same name as a function (such as i, j, mode, char, size, and path). In general, variable names take precedence over function names. If...

In this text we have given examples of very simple output and sometimes quite elaborate output. We now consider the input of text and data via the keyboard. An interactive way of obtaining input is to use the function input. One form of this function is >> variable = input('Enter data:...
Vectors: only one dimension Matrices: two or more dimension Size of array: row number ×column number The regulation of variable name: It must begin with a letter, followed by any combination of letters, numbers and the underscore character. Programming practice: Always give your variables ...
