public readonly struct Memory2D<T> : IStorage2D<T, MemorySlice<T>, Memory2D<T>>,
IStorage2D<T, Memory2D<T>>, IStorage2D<T>
- Implements
- IStorage2D<T>, IStorage2D<T, Memory2D<T>>, IStorage2D<T, MemorySlice<T>, Memory2D<T>>
Type Parameters
- T
- The element type of the array.
Remarks
Use the Memory2D<T> structure to represent two-dimensional arrays in a format suitable for calling external libraries like BLAS and LAPACK. The two-dimensional array is stored in a linear block of memory. Columns are stored in contuguous blocks with a fixed number of elements between them.
Memory2D<T> objects do not have a size. The actual dimensions must be supplied separately.
Constructors
Memory2D<T>(Int32, Int32, Boolean) | Constructs a new array. |
Memory2D<T>(Memory<T>, Int32, Int32) | Constructs a new array. |
Properties
Item | Gets or sets the element at the specified position. |
Leading | Gets the number of elements between the start of successive columns. |
Offset | Gets the position of the first stored element in the array |
Span2D |
Gets a 2D span over the elements of the array.
Return ValueA Span2D<T>. |
Methods
AsSlice | Returns the array as an array slice with unit leadingDimension. |
Clear | Sets the specified number of elements to their default value. |
Clone | Creates a deep copy of the array. |
Clone | Returns a new contiguous 2D array with the specified elements of the current array. |
Column | Returns an array with offset that corresponds to a column in the array. |
Column | Returns an array with offset that corresponds to a column in the array that starts at the specified position. |
Diagonal | Returns an array slice that corresponds to a column in the array. |
Equals | Indicates whether this instance and a specified object are equal. (Overrides ValueType.Equals(Object)) |
From( | Returns the array starting at the specified position. |
From( | Returns the array starting at the specified position with the specified leading dimension. |
Get | Returns the hash code for this instance. (Overrides ValueType.GetHashCode()) |
Get | Gets the index in the storage array of the element at the specified position. |
Get | Gets the Type of the current instance. (Inherited from Object) |
Resize | Returns a new array with the specified size and leading dimension. Elements are copied to the new array. |
Row | Returns the array slice that corresponds to a row in the array. |
Row | Returns the array slice that corresponds to a row in the array that starts at the specified position. |
Slice | Returns an array slice with a specified stride that starts at the specified position. |
Span |
Gets a span over the elements of the array.
Return ValueA Span<T>. |
ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType) |
Transpose | Transposes the elements of the 2D array and returns the result. |
Transpose | Transposes the elements of the 2D array and returns the result in the specified array. |
With | Returns the array at the current position with the specified leading dimension. |
Operators
Equality( | Checks whether two 2D arrays are equal. |
Inequality( | Checks whether two 2D arrays are not equal. |
