How to print a variable in matlab
Accepted Answer. Of course there is no correct answer because these are binary floating point values, but here is one solution that gives the "least unexpected" output. It assumes double values and upto 15 significant figures. chr = reshape (sprintf ('%.14e',abs (arr)), [],numel (arr)).';I am now trying to print this id value (class 'double') to the command line, if it doesn't have an assigned stress value, so if the isempty statement is True, prior to continuing out of the loop. As an example, if I set num_ids equal to 101, but the list I'm iterating through only has ID values 1-100, I want to output this 101 ID to the command ...warning (msg,A) displays a message that contains formatting conversion characters, such as those used with the MATLAB ® sprintf function. Each conversion character in msg is converted to one of the values A. warning (warnID, ___) attaches a warning identifier to the warning message.

how does one print a value of a variable to the command window?I know the disp command shows the values without the variable name and the fprintf command allows you to print a string with variables. But I'm trying to sort variables from highest to lowest and I want to get Matlab to print their corresponding variables rather than just giving me numbers. thanks!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.@HansHirse's answer is excellent. Another alternative using repmat below. Could have compacted the code a bit but left in its current form for accessibility. ** Alternative Approach: ** repmat
Yes. Add outputs to your function if variables are immediately needed in other functions or scripts. Otherwise, you can save any (or all) variables within a function by calling save (filename,variables) at the end of the function (for troubleshooting purposes). If you are running a script, any variables within the script are already available ...If you want to see the variables in a function workspace, then you have two main ways to achieve this: return some variables (i.e. output arguments) from a function to another workspace. use the debugging tools to view inside any workspace. This is explained in the documentation too: "By default, the Workspace browser displays the base workspace.Printing values to the command window. how does one print a value of a variable to the command window? You got it backwards. Typing the variable name first and then running the code will likely get you a "variable name not defined" error message.MATLAB - Checking type of variables. class() exactly works like Javascript's typeof operator. To get more details about variables you can use whos command or whos() function. Here is the example code executed on MATLAB R2017a's Command Window.3.1 User Input. The simplest way to request information from the user of a MATLAB program is with the function, input() . This function displays a prompt ...
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.Feb 24, 2017 · Answers (2) The return is 6.5003e-05 and the standard deviation is 0.0207. read the fprintf help page to get printing options based on the number formats.

S in symstr is replaced by its value. displayFormula (symstr) 1 + e 2 π i + e 2 π i 2 + cos ( e 2 π i) To evaluate the strings S and symstr as symbolic expressions, use str2sym. S = str2sym (S) S = 1.If you want to get all of the output values, you will have to call answer in the following way: [out1,out2,out3] = answer (1,2); This will place the value d in out1, the value e in out2, and the value f in out3.
