creating an empty cell in an array

i have an array most made up of numbers and some are NaN i would like to make the NaN cells empty because i have a plotting function that doesnt accept NaN and when i assign it to 0 it affects the resulting graph, so im not really sure of how to make it blank with no numerical value

i am using R2019a
Can’t you just ignore NaN values using isnan() ?
a = [1,2,NaN,5,NaN]
b = [3,4,5,1,NaN]
result = ???

Then use this code.
A = [1 NaN 2];
B = rmmissing(A) % will remove NaN from array A
The B array wil be [1 2]

the problem with this is that im plotting 2 different arrays where Nan in one array might be an actual value on the other so this will make the data miss match
Then you can ignore the corresponding values in the second array .
