In this example, we will learn how to use the disp function when we have multiple variables. To display a text in MATLAB, we use disp function which displays the text or value stored in a variable without actually printing the name of the variable. As we can see, the output has values that are derived from multiple variables. Unable to complete the action because of changes made to the page. The default font Any suggestions? The option For example, 500 grams or 4.7k Ohms. This table lists the named color units, set the Units property for the the sprintf or fprintf functions I think there's something I'm not understanding about output arguments. Accelerating the pace of engineering and science. so you want to display mu and m? text(x,y,z,txt) positions How to use disp command or disp function in matalab. variable = ['hello this is x' x ', this is now y' y ', finally this is d:' d], variable = [str1 str2 str3 str4 str5 str6]. I found the solution to the problem from a user in Stackoverflow. So, I had to opt for string-method to put the additional information on the plot. MathWorks is the leading developer of mathematical computing software for engineers and scientists. Consider replacing the text edit fields with numeric edit fields, For edit field area, I have used Numeric and I have done like this code, No public property EIRP2 exists for class LinkBudgetApp. Nope, num2str makes it difficult to work. text (x,y,z,txt) positions the text in 3-D coordinates. How do I iterate over the words of a string? character vectors, string array, symbolic number, variable, expression, or array. But still a minor issue remains. Not the answer you're looking for?

With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. Otra forma de mostrar una variable es escribir su nombre, que muestra " X = " delante del valor. Your approach is fundamentally flawed because you are storing meta-data in the variable names: trying to access that meta-data will make your code complex, slow, and hard to debug. Bulk update symbol size units from mm to map units in rule-based symbology, Surly Straggler vs. other types of steel frames. Ben, that should work if you put enough significant digits: 'For x=-20 the true value of e^x is: %.22f\n', For x=-20 the true value of e^x is: 0.0000000020611536224386, 'For x=-20 the true value of e^x is: %g\n', That's a pretty small number. x and y must be equal Other MathWorks country You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance.
