lingo 经典程序哪里有？
function y=mminterp(tab,col,val)%MMINTERP 1-D Table Search by Linear Interpolation.
% Y=MMINTERP(TAB,COL,VAL) linearly interpolates the table
% TAB searching for the scalar value VAL in the column COL.
% All crossings are found and TAB(:,COL) need not be monotonic.
% Each crossing is returned as a separate row in Y and Y has as
% many columns as TAB. Naturally, the column COL of Y contains
% the value VAL. If VAL is not found in the table, Y=[].

这有一点，程序和解法都有介绍 只用matlab够不够啊 实际问题出现了再现学现卖哈~ awegdrjhntyjmygfvthf ooooooooooooooooooooooooooo aaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaa啊啊啊啊啊、 不知道啊啊
