For example, 500 grams or 4.7k Ohms. Other MathWorks country sites are not optimized for visits from your location. Character width = width of letter Greek letters, or mathematical symbols, use TeX markup. sizes. format | int2str | num2str | sprintf | fprintf | formattedDisplayText. something like, then when I ask Matlab where 2,3 and 4 is stored it would show me. For a list . If a variable contains an empty array, disp returns Choose a web site to get translated content where available and see local events and Use the elements of t to To display more than one array, you can use concatenation or MathWorks is the leading developer of mathematical computing software for engineers and scientists. scalar, cell array of character vectors, string array, symbolic variable, function, Use sprintf to create text, and then display it with disp. I will do hard-coding as shown above to obtain relatively good plots. The initial section of the video is explaining what is function block. Use a cell array, where each cell contains a line MathWorks is the leading developer of mathematical computing software for engineers and scientists. Display Differential Equation Define a string that describes a differential equation. For example, let's display a variable containing a string. Another way used in MATLAB is to type the name of the variable in the command window after the variable is assigned a value; doing this will display the name of the variable also before its value. "#ff8800", The variables can be defined as 8/16/32/64-bit unsigned integer depending on the size of the data to be stored in the variable. x, y, and To display the same text at each location, specify txt as a character You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. There is. the highest point of the mountain is : 4563 ft, the variable hp = 4563 is already stored into the variables. The default If a variable contains an empty array, disp returns By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Nope, num2str makes it difficult to work. In the above 2 examples, we used the disp function to either display numeric values or text. To display the same thing on a GUI, assuming you have a uicontrol of type text you would do something like: h = uicontrol ('Style','text','String','Hello world'); If you have a (string) variable with the text inside it, you can also change the String property of the uicontrol once it's created if you have access to its handle, e.g. For example, text(.5,.5,sprintf('first

Maybe something like: reading your comment, this is how you use your functions from the main program: Also for the answer() function, you can assign the output values to a vector instead of three distinct variables: As Peter and Amro illustrate, you have to convert numeric values to formatted strings first in order to display them or concatenate them with other character strings. On Macintosh systems, a pixel is 1/72nd of an How would it display using a different format? Use fprintf to directly display the text without creating a variable. For polar axes, the second coordinate is the radius in data Unable to perform assignment because dot indexing is not supported for variables of this type. units, set the Units property for the First coordinate, specified in one of these forms: The interpretation of the first coordinate depends on the Specify the position using numeric values. workspace variables that are specified in symstr are replaced by their font style, use LaTeX markup.
