Command Function will not accept the script name. I have tried changing the function name so it is different from the script but this still does not work.

%Setup Matlab Script

function plotctd(datafilename)
Data = dlmread(datafilename,'',117,1);
Depth=Data(:,1);
Salinity=Data(:,2);
Temp=Data(:,3);
%calculating density
Density=sw_dens0(Salinity,Temp);
%Subplot of data
subplot(1,3,1)
plot(Temp,Depth,'k-+')
set(gca,'YDir','reverse')
xlabel('Temperaure (^oC)')
ylabel('Depth (m)')
grid
subplot(1,3,2)
plot(Salinity,Depth,'k-+')
set(gca,'YDir','reverse')
xlabel('Salinity (PSU)')
grid
title(datafilename)
subplot(1,3,3)
plot(Density,Depth,'k-+')
set(gca,'YDir','reverse')
xlabel('Density (kg/m^3)')
grid
plotctd('D1.cnv')
end
This code gives me the error message:
File: plotctd.m Line: 6 Column: 10
Local function name must be different from the script name.

It would be easier on the volunteers if you were to post code instead of posting pictures of code.
Delete your current line 31, which reads
plotctd(D1.cnv)
Now, create a new file, perhaps plot_D1.m that contains
plotctd('D1.cnv')
and execute that file.

@Luke Ainsworth: you have defined a recursive function which only stops because of invalid input data.
Solution: do not call PLOTCTD inside the function PLOTCTD.
You also need to call the function with a valid filename as its input argument.
