Introduction To MATLAB Interactive Graphics
There are two ways of storing text into a MATLAB variable For many applications you can use either type The main difference between the two is how they behave when you put then into an array Character Arrays A character variable holds a single text character To create a character variable, put the character between single quotation marks
Scalars and Variables
string str = "This is a character string"; Variable Represents ans Variable that has the value of the last expression that was not assigned to a specific variable If the user does not assign the value of an expression to a variable, MATLAB automatically stores the result in ans pi The value of eps The smallest difference between two numbers

typing the name of a variable will display its value (of course, the value can also be seen in the Workspace Window) >> mynum þ 3 ans = 10 >> mynum mynum = 7 1 3 1 Initializing, Incrementing, and Decrementing Frequently, values of variables change, as shown previously Putting the first or initial value in a variable is called initializing
Converting Numeric and Character Data
Because a character variable can hold both alpha and numeric data sometimes it make it difficult to convert the data If you have any non-numeric character in the character variable the output will be missing and your log will contain a NOTE: Invalid Data message everytime you have a non-numeric character in your data So you could get 10,
