shows that the result is a 1x33 character array (made up of the ASCII decimal codes for each number and the period.) Try >> x_d = double(x). To convert to a number that can be used in subsequent calculations, we must use the “str2num” (convert string to number) command: >> x_d = str2num(x)

It is often necessary to also convert integers and real numbers to characters. However, there is no intrinsic function in Fortran to do this. To do this we need to use a . minor Fortran trick. Let’s assume we want to loop through an integer (say from 1 to 10) and append the number of the loop to a character string. The following example shows ...

y = nan; %% stands for not a number . end Character Strings: In MATLAB, these are arrays of ASCII values that are displayed as their character string representation. For example: >> t = ‘Hello’ t = Hello >> size(t) ans = 1 5. A character string is simply text surrounded by single quotes. Each character in a string is one element in the array.

More importantly, each MATLAB variable may be an array with purely real or complex elements. For example the statement below declares A to be a 4 by 2 matrix of real numbers (there appears to be no distinction between real numbers and integers): ... ” character on a line, the rest of the line is taken as a comment. ...

When the size argument is a scalar n, fscanf reads at most n number, character, or string values from the file. The output matrix contains at most n rows. fscanf fills the output matrix in column order, using as many columns as it needs to represent all the numbers and characters read from the input.

Matlab does not require any type declarations or dimension statements! eg: >> num_students = 25. creates a (1-by-1 matrix!) variable named num_students and stores the value 25 as its only element. Variable names consist of a letter, followed by any number of letters, digits, or underscores. eg abc123 or abc_123. Numbers

The num2str command is the command that will convert a number into the corresponding text character. Note the difference between: >> num2str(1) and >> char(1) There are a bunch of useful functions that can be used with strings. I recommend reading about strfind and strcmp (and regexp if you already can guess what that function will do).

18) Store a number with a decimal place in a double variable (the default). Convert the variable to the type int32 and store the result in a new variable. >> num = 13.45. num = 13.4500 >> intnum = int32(num) intnum = 13 19) Generate a random. real number in the range from 0 to 1. rand. real number in the range from 0 to 20. rand * 20
