[Numpy-discussion] in-situ resizing array in C

Hi, I have a question to Numeric/Numarray experts: Let A be a contiguous one or two-dimensional array with shape (n,) or (m,n), respectively. Let k be a positive integer less than n. Reference count for A is 1. The objective is to execute A=A[:k] or A=A[:,:k], respctively, in C. Q: Is it safe to resize the array A by simply resetting its dimensions, that is, A->dimensions[0] = k; or A->dimensions[1] = k; if A->nd is 1 or 2, respectively, in C? This appears to work but may be there are some corner cases that I have overlooked. Would that work also when using Numarray? If not, how to resize (preferably in-situ) an array in C under the conditions given above? TIA, Pearu
