"Invalid color or line style." Error during plotting in Executable
显示 更早的评论
I am trying to plot a figure with an executable created by "compiler.build.standaloneApplication".
The function I am using is;
function dummyFunction1(a,b)
plot([1 2],[a b]);
end
And the code for executable generation;
appFile = fullfile('D:\testFolder\dummyFunction1.m');
opts = compiler.build.StandaloneApplicationOptions(appFile,'OutputDir','D:\testFolder');
results = compiler.build.standaloneApplication(opts);
Here is the problem;
Any help would be great.

Read the "Using a MATLAB File You Plan to Deploy" section on this documentation page. Inside your application as you've written it a and b are not the numbers 5 and 8 but the char arrays '5' and '8', and '58' is not a valid color or line style for the plot function (as the error message indicates.) You will need to convert them into numbers before using them in your call to plot.

Hi Steven, thank you. The link helps me to modify the function.
The key point is command prompt takes inputs as a character array.
function dummyFunction1(a,b)
a_double = str2double(a);
b_double = str2double(b);
plot([1 2],[a_double b_double]);
end
You probably want to use the isdeployed function to only convert from string to number in your deployed application, or use the ischar and/or isstring function to only convert if you receive text data as input. If given a number as input the str2double function will return NaN.
str2double(5)
x = '5';
if ischar(x)
fprintf("Input data is a char")
x = str2double(x);
else
fprintf("Input data is a number")
end
class(x)
x = 8;
if ischar(x)
fprintf("Input data is a char")
x = str2double(x);
else
fprintf("Input data is a number")
end
class(x)

you should check the color or line style in dummyFunction1 and change both by some other vlue and then run the program and check the output result.
