Help Center Help Center. If A contains complex numbers, isnan A contains 1 for elements with either real or imaginary part is NaN , and 0 for elements where both real and imaginary parts are not NaN. Create a row vector and determine which elements are NaN. Create an array of complex numbers. Determine whether the complex numbers contain NaN. Create an array and find the elements with NaN values. Replace the NaN values with 0. If x is a real scalar, exactly one of isfinite x , isinf x , and isnan x returns logical 1 true. For a complex scalar z , isinf z and isnan z can both return logical 1. This function fully supports tall arrays. For more information, see Tall Arrays. This function fully supports thread-based environments. This function fully supports GPU arrays.

Because the 1st column has just one NaN on row 2, and the 2nd column has NaN for row 3 and 5. Would there be simple ways of counting how many NaN's occur, and identify their location in a given matrix? If A contains complex numbers, anynan A returns 1 if at least one element has a real or imaginary part that is NaN. Thanks for jump-starting my thinking! Search Answers Clear Filters.
