Attempt to execute SCRIPT scatter as a function: F:\MATLAB\​R2019a\too​lbox\m

Hello all,

I keep getting this error message below

Attempt to execute SCRIPT scatter as a function:

F:\MATLAB\R2019a\toolbox\matlab\specgraph\scatter.m

Note: I have checked the "specgraph" folder and delete the "scatter.m" file, but i keep getting the above error message.

Please is there any other means to handle this issue? Thank you

See this answer.

[Cris LaPierre]

This file F:\MATLAB\R2019a\toolbox\matlab\specgraph\scatter.m is MATLAB's function for creating scatter plots. It should be a function, not a script, and you probably shouldn't be modifying it.

Please share the complete error message (all the red text)

[CHARLES ADDEY]

I was trying to do this when i got the error

% dummy data
n = 50;
x = linspace(112,120,n)+0.25*rand(1,n); % Longitude 
y = linspace(22,24,n)+0.5*rand(1,n); % Latitude
z = 10+y; % temperature

figure(1),
scatter(x,y,z,z,'filled');
colormap('jet');
colorbar('vert');

The error from the red text is the four lines below

Attempt to execute SCRIPT scatter as a function:

Error in Gridd_and_average (line 11)

Pleaes run the script. If you still get the error, share the result of the following code.

pwd
which scatter -all
type scatter.m

[CHARLES ADDEY]

Here is the result

>> pwd

which scatter -all

type scatter.m

ans =

Have you recovered the file you deleted?

• F:\MATLAB\R2019a\toolbox\matlab\specgraph\scatter.m

[CHARLES ADDEY]

Yes, I have recovered it, i still get the error message

Undefined function 'scatter' for input arguments of type 'double'.

Error in Gridd_and_average (line 11)

scatter(x,y,z,z,'filled');

[Cris LaPierre]

Somewhere you have a script named scatter.m that is being called instead of the plotting function scatter. Perhaps the script you are working in? If so, try renaming your script.

If the file is restored, repeat the last 2 commands above and share the result.

[CHARLES ADDEY]

Hi Chris, the result of the last command is shared below.

ERROR MESSAGE

%SCATTER Scatter plot.

% Supported syntaxes for tall X, Y:

% SCATTER(X,Y)

% SCATTER(X,Y,S)

% SCATTER(X,Y,S,C)

% SCATTER(...,M)

% SCATTER(...,'filled')

% SCATTER(AX,...)

%

% Notes and Limitations:

% 1) S must be scalar or empty

% 2) C must be scalar or RGB triplet

% 3) Categorical inputs are not supported.

% 4) With tall inputs, SCATTER plots in iterations, progressively

% adding to the plot as more data is read. During updating, a progress

% indicator shows the proportion of data that has been plotted. Zooming

% and panning is supported during updating before the plot is complete.

% To pause the update process, press the pause button in the progress

% indicator.

What is z?

whos z

Why are you passing in z into scatter() twice?

scatter(x,y,z,z, 'filled'); 

[Cris LaPierre]

What version of MATLAB are you using? Your error message suggests R2019a, but if so, that is not the 2019a version of scatter.m.

[CHARLES ADDEY]

I am using R2019a, probably i might have mixed up the scatter.m somewhere along the line while trying to resolve this issue.

Is there a way to reset the R2019a to the default installation state, or I should just uninstall and reinstall back. Thank you Cris

[Cris LaPierre]

I'd suggest uninstalling and reinstalling. It may be possible to work out another way, but it would take much longer to work out via comments here.

Typically this error message happens when you save your script using the same name as MATLAB's function name. However, the tests above show that doesn't appear to be the case. Just thought it was worth pointing out so that you can be sure to avoid using those names going forward.

[CHARLES ADDEY]

Thanks again Cris

[Walter Roberson]

scatter(x,y,z,z, 'filled'); 

is valid. It would use z as the spot size and also as the color indication.
