Why do I receive errors using IFANBEAM for matrices with NaN

Why do I receive errors using IFANBEAM for matrices with NaN values in Image Processing Toolbox 7.2 (R2011a)?

I am trying to use the function IFANBEAM on a matrix with NaN values and receive a warning and an error depending on how many NaNs the matrix contains. An example of the code, warning and error message follow:

A = rand(10, 10);

b = 100;
good_result = ifanbeam(A, b);
A(10, 1:9) = NaN;
some_result = ifanbeam(A, b);
A(10, 10) = NaN;
bad_result = ifanbeam(A, b);

Warning: NaN found in Y, interpolation at undefined values

will result in undefined values.

The ability to compute the inverse fan-beam transform using IFANBEAM function when the input matrix has a row of NaN values is not available in MATLAB.

The IFANBEAM code works by doing interpolation then by calling IRADON. In this example, the error happens during the interpolation step in FAN2PARA. When there are NaN values, interpolation fails. The warnings and errors come from code in MATLAB’s INTERP1 function. In some cases, INTERP1 can attempt to ignore NaNs to do its job interpolating. However, if there are too many NaNs, it cannot produce good results. In both cases, the resulting values will not be meaningful as the NaN values will just spread around.
