可重覆執行指令若干次。當 expression
的實數部分都不是0時,指令就會被執行。expression 通常是下列格式
expressionropexpression
rop 為 ==, <, >, <=, >=, or ~=.
Examples
eps is a tolerance used to determine such things as near singularity and rank.
起始值是machine epsilon, 為 1.0
到比下一個比1.0略大而且可以在你機器上表示出來的浮點數的差距。 可利用 while 廻圈來求之:
eps = 1;
while (1+eps) > 1
eps = eps/2;
end
eps = eps*2
