Ignore NaN value when iterating

Hello, say for example I would like to iterate each row, and ignore any NaN values in a matrix.

For example a 3x5 matrix (A):

[1 2 3 4 5 ]

[1,NaN,NaN,NaN,NaN]

[1 2 3 NaN,NaN]

I want the length of each row without NaN for iteration.

Hence the result will be:

[5]

[1]

[3]

for i = 1:size(A,1)
%     I want the length of each row without NaN values
    nonan = length(A(i,isnan(A)==0))
%     Then use that for another for loop...
        for 1:length(nonan)
            ...
        end
end

How can I code this? Thanks in advance.

arrayfun(@(x)numel(A(x, ~isnan(A(x, :)))), 1:size(A,1))
