Print a statement to the Command Window

I am writing a program. I want to display the statement 'job done' as the output in the Command Window. How can I do it?

Hai navneet nayan,

disp('job done');

disp command is used display the string values.

To display text in the Command Window, use disp or fprintf.

disp('job done')

or

fprintf('job done \n')

I would not mark this as an accepted answer since it does not solve the problem I detailed.

Hi John,

There is no way to direct output to the Command Window from a live script that you run in the Live Editor.

You can run the live script from the command line; e.g., if your file is myScript.mlx, then

>> myScript

will indeed output to the Command Window (and separate figure windows). But again there's no way to redirect output from the Live Editor. This is something we are investigating, however.

I just wanted to bump some support for such a feature with live editor. with some larger scripts that can take up to hours of runtime it would be nice to be able to push a "N% complete" or "Error Detected" flag to the window. Not required but would be nice to be able to have the same color options matlab uses for the command window, i.e. disp in default text options with a vargin for red text etc.

It's not happening. How to display LHS=RHS?

[Christopher Johnston]

As mentioned by KSSV, you can use fprintf.

For the variables you have shown above:

fprintf('a = %.4f \nb = %.4f \nx = %.4f \n', a, b, x)

This example allows you to print to 4 fixed points of precision, but this can be tailored to your need by changing the number after the '%.' .

[Steven Lord]

Even though a and b are displayed the same, that doesn't mean their contents are the same. The == operator checks for exact down-to-the-last-bit equality. In this case, a and b are close but close doesn't count. See this Answers post for an alternative.

[sidway]

Try to make a diference between a and b with a tolerance

tol = 1e-3
if abs(a - b) < tol
    disp('LHS=RHS')
end

Use the disp function to print to the command window:

disp('job done')

job done

[John Taranto]

Please help me understand this. I use Live Scripts to write my Matlab code. There is a window titled Live Editor - with the path to the mlx file. Separately, there is a Command Window. When I use either the disp() or fprintf() function the output is to the Live Editor Window. I would like to output to the Command Window. How would I do that?

Thanks.

I agreen with @John Taranto. On a .mlx script disp or fprint do not return anything in Command Window, instead it is returned directly underneath the code or to the side depending on your setting. Is there a way to force the text to be displayed in the command window? Thank you in advance
