How can I make a cdf plot?
显示 更早的评论
I am trying to make a CDFplot for a box dimensions but I am getting an error because I have 1+ in my depth column. How can I search for the + and replace it with to 1.1.
At the moment my script is :
load ('MyFileName.mat')% this is an example tilte
figure; % depth
cdfplot(MyFileName.boxDepth);
title(Box Depth)
xlabel('Depth (m)')
ylabel(cdf)
The error I am getting is:
Undefined function 'isnan' for input arguments of type ' categorical'.
Error in cdfcalc (line 39)
x=x(~isnan(x));
Error in cdfplot (line 41)
[yy,xx,~,~,eid] = cdfcalc(x);
Thank you

You've shared the wrong code. The error is in your cdfplot function.
There appears to be a datatype error as well. Perhaps because one of the values is "1+", your data is categorical. It makes it easy to rename the wrong category - use renamecats. I imagine for a cdf plot you need the data to be numeric not categorical. You could use str2double to convert your variable.
You could also just keep your data double, which would likely assign this element a value of "NaN". You could then use fillmissing.

You'll find examples of how to use the functions I mentioned in each of the linked documentation pages. Look for "Examples" in the left hand navigation menu.
