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.disp(X) displays the value of variable X without printing the variable name. Another way to display a variable is to type its name, which displays a leading “X =” before the value. If a variable contains an empty array, disp returns without displaying anything.how to use fprintf to print strings and words. Learn more about fprintf .

Specifying the Model to Print. To print a noncurrent Simulink model, use the option with the title of the window. For example, this command prints the Simulink window titled.Like Colin mentioned, one option would be converting the numbers to strings using num2str, concatenating all strings manually and feeding the final result into disp.Unfortunately, it can get very awkward and tedious, especially when you have a lot of numbers to print.. Instead, you can harness the power of sprintf, which is very similar in …There are few work arounds: change connection to database functions so that login info wouldn't be printed (however they are not in matlab format, so difficult to change) or instead of using command window, create some txt file, write all info I want to show to it and automatically open it. But I hope there is a simple command to do it.Guard Digits. The number of digits that you specify using the vpa function or the digits function is the guaranteed number of digits. Internally, the toolbox can use a few more digits than you specify. These additional digits are called guard digits.For example, set the number of digits to 4, and then display the floating-point approximation of 1/3 using four …The name of the variable should not matter. Not that it is "varname" in every case here. But the name might be different in the caller. Nevertheless, relying on the name is a pitfall. Better create a specific variable, which carries the name:For example, MATLAB uses 3 digits to display int8 data types (for instance, -128:127). Setting the output format to short or long does not affect the display of integer-type variables. Integer-valued, floating-point numbers with a maximum of 9 digits do not display in scientific notation.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. The result is much as-if ...1. In case you just want to use the first 2 decimals, you can add this line to your previous code: out (:) = str2num (sprintf ('%6.2f',out (:))); % 2 = number of decimals. This is not a beautiful solution but it truncates your values to the 2nd decimal and stores it erasing the following decimals. You will still have some zeros at the end (till ...thanks but i still want to keep the other legend and it wont let me make 2 of them. but i think i found an okay way of doing it by adding a blank subplot, turning the axis off and then adding a text box into the middle of the blank plot.To view the variables in the workspace, use the Workspace browser.
