How Matlab removes the Nan values from the array

? ? For example, we have a set of data, there are a lot of Nan value, how to delete it? Can be done by the find function.

?? We can import the data file Data.txt into array A by importdata (' Data.txt '). ? ? ? ? ? ? ? ? ? ? ? ??? A=importdata (' data.txt ') ?? and then through the command? ? ? ? ? ? ? ? ? ? ? ? ?Z=find (~isnan (A))to find out the number of Nan in the A array;? ? ? ? ? ? ? ? ? ? ? ? ? ?? B=a (z)You can eliminate all the Nan values in a, and if you want to get numbers for non-nan values, then Z is! ????????? If only the Nan value in A is removed, then b=a (~isnan (A)) can be done!
