Hi, i have a matrix 7938x498 with numerical and NaN values. I want to change value to some NaN elements but i don't know exactly their index in the matrix. I make an example to explain it better.
if i have a vector like this A=(NaN,NaN,NaN,NaN,NaN,1,5,7,9,NaN,NaN,NaN,NaN,5,5,53,3,NaN,NaN). How can i change the NaN values beetween 9 and 5 without change the others? Thanks

dqb i only need that they are finite. Doesn't matter the exact value

that's part of the matrix. I need to change the value 3985 and 3989 from second column

Here is one way:
% The original data
A = [NaN,NaN,NaN,NaN,NaN,1,5,7,9,NaN,NaN,NaN,NaN,5,5,53,3,NaN,NaN];
% The indices of the numeric values
numericIndices = find(~isnan(A));
% The indices of the NaNs in the gap between the numeric values
gapIndices = setxor(min(numericIndices):max(numericIndices),numericIndices);
% Fill in the values you want to assign
A(gapIndices) = ...
