while the statement “no such method in ILMath” is correct, one can utilize a simple assignment from System.Array to any ILArray of the element types listed above. This will trigger very similar things under the hood of the Computing Engine. However, if performance is really important for your large data, consider using the unsafe method above. As always: use a profiler and compare…

While the statement ‘there is no method in ILMath’ is correct, another option exists for converting most (all?) numeric datatypes to any datatype supported in ILNumerics: a simple assignment.

The implicit conversion operator allows to assign System.Array (1 dimensional and multidimensional) to ILArray, where T is any of the types supported and listed above. The conversion will
basically do similar things as given in this example. However, the Convert class from the .NET framework is used which involved at least another function call for each element. Also, the iteration will be less efficient than the version given here. This may or may not be significant for your application. As always: a profiler is your friend.
