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.

Help Center Help Center. For example, NaN 3,4 returns a 3-by-4 matrix. For example, NaN [3 4] returns a 3-by-4 matrix. You can specify typename or 'like' but not both. Create a 2-byby-4 array of NaN values and display its size. Create an array of NaN values that is the same size as an existing array. Create a 1-by-3 vector of NaN values whose elements are of type single. You can also specify the output type based on the type of another variable. Create a variable p of type single. Then, create a vector of NaN values with the same size and type as p.

By default, the codistributed array has the underlying type double. MathWorks Answers Support.

Help Center Help Center. Specify codist as "codistributed" to use the default codistributor1d distribution scheme or the distribution scheme defined by a codistributor1d or codistributor2dbc object. When you create the codistributed array in a communicating job or spmd block, the function creates an array on each worker. If you create a codistributed array outside of a communicating job or spmd block, the array is stored only on the worker or client that creates the codistributed array. For example, NaN [2 3],"codistributed" creates a 2-by-3 codistributed array.

Help Center Help Center. Infinity results from operations like division by zero and overflow, which lead to results too large to represent as conventional floating-point values. Use the isinf function to verify that x is positive or negative infinity:. The exact bit-wise hexadecimal representation of this NaN value is,. Always use the isnan function to verify that the elements in an array are NaN :. However, in some special cases perhaps due to hardware limitations , MATLAB does not preserve the exact bit pattern of alternate NaN representations throughout an entire calculation, and instead uses the canonical NaN bit pattern defined above.

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. You can also specify the output type based on the type of another variable. If you specify typename as 'codistributed' or 'distributed' , the default underlying type of the returned array is double.
