I have plotted x and y data and seen evidence of a bifurcation. I want to plot x vs diff y.
this is what i did :
this is what i got:
Error using plot
Data must be numeric, datetime, duration or an array convertible to double.
is it possible to plot x data and y differential?

yes thank you. can you tell me how to print diff y into a third column (v) ? i will perform the work on the .mat file to save you doing it.

Please upload the .mat file containing the variables nslogistic and y.

diff(Y) function calculates the difference between adjacent elements of Y along the first array dimension whose size is not equal 1. But to find the derivative of Y with respect to X you can use diff(Y)/h where h is the step size in X, if X doesn’t have equal step size then you can use diff(Y)./diff(X).
While using plot function make sure that the data type of the input arguments must be one of these type single, double, int8, int16, int32, int64, uint8, uint16, uint32, uint64, categorical, datetime, duration
