object strideMatInstantiateCheck
strideMatInstantiateCheck performs a set of safety checks when constructing a matrix view with arbitrary strides and offset into a backing array. The checks include:
- Ensuring the number of rows and columns are positive.
- Ensuring the offset is within the bounds of the backing array.
- Ensuring both rowStride and colStride are non-zero.
- Calculating the maximum and minimum indices that could be accessed by the matrix view, given the strides and offset, and ensuring these indices are within the bounds of the array.
- Throws appropriate exceptions if any check fails.
Validates matrix construction parameters for stride-based layout.
Performs comprehensive bounds checking for matrices with flexible stride patterns, including support for broadcasting (zero strides) and negative strides for flipped views.
Validates:
- Positive matrix dimensions
- Valid offset within array bounds
- Sensible stride values (zero for broadcasting, non-zero otherwise)
- All matrix elements remain within array bounds
- Negative strides don't cause negative index access
- 1x1 matrices have semantically meaningful strides (0 or 1)
