MATLAB: Does the error “Attempt to execute SCRIPT settings as a function: C:\..\..\..\settings.m occur and how to fix it

Parallel Computing Toolbox

Why does MATLAB throw an error when executing one of the commands below?

>> parpool
>> parallel.Settings

Invalid default value for property 'ParalleNode' in class 'parallel.internal.settings.ParallelSettingsTree':

Attempt to execute SCRIPT settings as a function:

"C:\Users\..\..\settings.m"

Best Answer

One of the reasons for this error is the user's file named "settings.m" file in "C:\Users..\..\" directory as shown in the error message. When executing the commands like "parpool", MATLAB is trying to access its built-in script "settings.m". In this case, it is being shadowed by "settings.m" in the "C:\Users\..\.." directory and hence the error occurs.

The workaround is to rename the "settings.m" in "C:\Users\..\.." to avoid name conflict with MATLAB built-in functions.

MATLAB: Do I get an error when setting the LineStyle property for multiple lines in MATLAB 7.4 (R2007a)

The "LineStyle" property for a line object only accepts values of '-', '--', ':', '-.' or 'none'. You can use the "Marker" property to separately set marker symbols. To illustrate, here is an example:

h = plot(rand(10,6))
set(h, {'LineStyle'}, {'-';'--';'--';':';':';':'})
set(h, {'Marker'}, { 'none'; 'o'; 'x'; 'none'; 'none'; 'none'; })

For further help with Line properties in R2007a, refer to the corresponding documentation:

For your reference, here is a link to the corresponding documentation for a more recent MATLAB version, e.g. R2018b:

MATLAB: Setting Default Properties for a Colorbar Label

As of MATLAB R2017b, it is not possible to set property defaults that apply to the colorbar label.

As a workaround, you can set the properties of the colorbar label after the colorbar has been defined. For example, you can use the following code to set the interpreter for the colorbar label:

>> figure;
>> cb=colorbar;
>> cb.Label.Interpreter='latex';
