Write a NumPy program that creates a 2D NumPy array and uses slicing in combination with index arrays to select a rectangular subarray. Click me to see the sample solution 15. 3D Array & Boolean Indexing for Value Replacement Write a NumPy program that creates a 3D NumPy array and uses bool...
Note: In 3D arrays, slice is a 2D array that is obtained by taking a subset of the elements in one of the dimensions. Let's see an example. importnumpyasnp# create a 3D array with shape (2, 3, 4)array1 = np.array([[[1,2,3,4], [5,6,7,8], [9,10,11,12]], [[13,...

This has the same functionality as SystemInfo.hasDynamicUniformArrayIndexingInFragmentShaders and also mimics platform-specific behavior in the Unity Editor.

Direct3D 12 dynamic indexing sample This sample demonstrates the use of new features available in HLSL's Shader Model 5.1—specifically, dynamic indexing and unbounded descriptor tables. With dynamic indexing, shaders can now index into an array without knowing the value of the index at compile ...
A compact index card register of relatively small dimensions, consisting of a housing with a keyboard of several selector keys arranged in an array of rows and columns, and within the housing a drawer adapted to be moved outwardly from the housing and to accommodate a stack of index cards. ...
