A MATLAB variable can only begin with a letter followed by underscore _ and numbers inside or at the end of the variable name. MATLAB is case sensitive, so A and a are not the same variable. Other symbols are syntactically invalid anywhere in a variable name. Examples of valid names are, x6. lastValue.Pretty Print Long Expressions Solve this equation, and then use pretty to represent the solutions in the format similar to typeset mathematics. For better readability, pretty uses abbreviations when representing long expressions.Do not change the type of the variables during the code. Better perform all calculations with numbers at first and display it once at the end: function price = fare(d, a) if d <= 1. ...

We can use the fprintf() or disp() methods. Use the disp() Method to Print Output in Command Window in Matlab. The disp() method displays the value of a variable in Matlab. For instance, disp(a) will display the value of the variable a without the variable name.Using this, you can create a short function that, given a variable, will output the name of it as a string, as in the following example: Theme. Copy. function out = getVarName (var) out = inputname (1); end. As long as the file is included on the MATLAB path, you can use the function in the following way: Theme.

There are three common ways: Type the name of a variable without a trailing semi-colon. Use the “disp” function. Use the “fprintf” function, which accepts a C printf-style formatting string. Here are examples: > x = [1 2 3 4]; > x x = 1 2 3 4 > disp (x) 1 2 3 4 > fprintf ('%i ', x) 1 2 3 4. Notes: Create 4 variables: len, wid, txt, area; In 'len' and 'wid' stores two numbers 2 and 3 respectively; Perform multiplication of 'len' and 'wid' and store the result in the variables 'area' In 'txt' store the character array 'The area is: ' Use disp() function to display 'txt' and 'area' together.In MATLAB Online™, print only prints to PDF.

Hence you need to use live scripts to use the subscript functionality.The fprintf function. The fprintf function is used for printing information to the screen. The fprintf function prints an array of characters to the screen: fprintf ('Happy Birthday '); We often use the fprintf statement to show the user information stored in our variables. To "place" a number into this string of printed characters we use ... Instead, the row %d consumes the first entry in r, the a = %d format entry consumes the second element in r, so "row 1, a = 2" gets printed out. Then next cycle, the row %d moves on to the next available item from memory, and having finished r, moves on to a, so you end up with "row 7, a = 13" as the second output line.
