"Attempt to execute SCRIPT polar as a function" error
显示 更早的评论
I am using R2015a version of Matlab. I have measured the flow velocities of a fluid at different points of a circular pipe. I looked up the examples of polar plots in Matlab and thought of entering the measurements in a polar plot. Since, I'm a beginner I thought of trying the sample code in the software's help directory
theta = 0:0.01:2*pi;
rho = sin(2*theta).*cos(2*theta);
figure
polar(theta,rho,'--r')
I ran the above commands in the command window directly and got this error.
Attempt to execute SCRIPT polar as a function:
D:\M\toolbox\matlab\graph2d\polar.m
Based on questions on similar problems, I realised that there is a file in my drive which shares the same name as the polar function. However, on searching I found 14 other files of the same name in the D:\M folder, all of them showing dates of 2014 and below. I wonder if these files are important for the software since the answers recommend deleting or renaming the files.
Would appreciate some assistance!

It seems like somehow the polar.m file accidentally got overwritten. Although you found 14 files, MATLAB still found the correct one on its path toolbox\matlab\graph2d\polar.m (this is the correct location of polar.m from the MATLAB toolbox), but somehow even that file is not correct. I suggest to uninstall MATLAB and delete the M directory before reinstalling MATLAB again.

Yes, I appear from you error message that those files are not on MATLAB's path and will not cause any issue unless you add them to the path.
I am not quite sure how to do that. Maybe something like this will help: https://www.mathworks.com/matlabcentral/answers/375341-contour-plot-of-polar-coordinates
