getnrmt¶

Purpose¶

Computes number of rows to read per iteration for a program that reads data from a disk file in a loop.

Format¶

nr = getnrmt(nsets, ncols, row, rowfac, maxv)
Parameters: nsets (scalar) – estimate of the maximum number of duplicate copies of the data matrix read by readr to be kept in memory during each iteration of the loop. ncols (scalar) – columns in the data file. row (scalar) – if row is greater than 0, nr will be set to row. rowfac (scalar) – nr will be reduced in size by this factor. If insufficient memory error is encountered, change this to a number less than one (e.g. 0.9). maxv (scalar) – the largest number of elements allowed in any one matrix. nr (scalar) – number of rows readr() should read per iteration of the read loop.
