subˈtabulate, v. Math.
[sub- 9.]
trans. To expand (a mathematical table) by systematic interpolation; to evaluate (a tabulated function) for a set of values of the argument in between the tabulated ones. Hence subˈtabulated ppl. a.; also ˌsubtabuˈlation.

III. 87 The differences of subtabulated values. Ibid. 93 Then..the original table is subtabulated over the range required to tenths, hundredths or thousandths. 1947 Math.

Hildebrand Introd. Numerical Analysis v. 146 This problem would occur..if a function were initially tabulated for increments of 0·1 in x and it were required to subtabulate the function for increments of 0·01. 1975 Nature 16 Oct. 541/1 The principle adopted in this project was to compute accurate values at rather widely spaced values of the argument, and to produce values at the required tabular interval by systematic interpolation or subtabulation. |
