If you want to get all of the output values, you will have to call answer in the following way: This will place the value d in out1, the value e in out2, and the value f in out3. The default value of [0 0 0] corresponds to black. Multiply the matrix by the scalar coefficient K^2. In your code, instead of just setting 'answer' to some string, set a variable using whatever code is dealing with your user's information. Another way to display a variable is to type its name, which displays a leading " X = " before the value. To display more than one array, you can use concatenation or the sprintf or fprintf functions as shown in the example, Display Multiple Variables on Same Line. With respect to getting ans = 3 as an output, it is probably because you are not assigning the output from answer to a variable. As we can see in the output, the elements of array A are displayed using disp function. You can do this using the functions FPRINTF, SPRINTF, NUM2STR, and INT2STR. the highest point of the mountain is : 4563 feetThe angle. 76 degreesThe initial. as you see, the are all diplayed in one line of text. scalar, cell array of character vectors, string array, symbolic variable, function, To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

'\n\nThe highest point of the mountain is %i.\n'. MathWorks is the leading developer of mathematical computing software for engineers and scientists. then MATLAB sets it to 0. Description. As we can see, the output has values that are derived from multiple variables. This function can be used in cases where our code is not very long or easy to understand, and there is no need of displaying the input variables. Plot a line. S = "m*diff (y,t,t) == m*g-k*y"; Create a string array that combines the differential equation and additional text. Other MathWorks country All fields can have different types of data whereas a single field should have some type of data. I just realized why I was having so much trouble - in MATLAB you can't store strings of different lengths as an array using square brackets. In general you should keep data together as much as possible, not split it apart. more information, see Run MATLAB Functions in Thread-Based Environment.
