In MATLAB 7.0 (R14), using a "space" as a delimiter (e.g. ' ') in conjunction with DLMREAD or TEXTREAD will result in two adjoint spaces introducing an empty ( [] ) number in the matrix result.
For example, if the input file is a single line "1 2", where there are two spaces between the 1 and the 2, then the vector created by DLMREAD will have three elements: 1, [], and 2.
