How do I fix NaN error in MATLAB?

percentage=abs(sum(k+1)-sum(k))/abs(sum(k+1)); and when the denominator abs(sum(k+1)) == 0, percentage is NaN. I don't know what you want to compute here, so you have to fix this yourself. And note that sum is a function in Matlab, so please do not use sum as the name of a variable.

What produces NaN in MATLAB?

These operations produce NaN : Any arithmetic operation on a NaN , such as sqrt(NaN) Addition or subtraction, such as magnitude subtraction of infinities as (+Inf)+(-Inf) Multiplication, such as 0*Inf.

How does MATLAB ignore NaN values?

Use the MATLAB^® function mean instead. With the mean function, you can specify whether to include or omit NaN values for the calculation.

How does MATLAB handle NaN?

Many MATLAB functions enable you to ignore missing values, without having to explicitly locate, fill, or remove them first. For example, if you compute the sum of a vector containing NaN values, the result is NaN . However, you can directly ignore NaN s in the sum by using the 'omitnan' option with the sum function.
