Question

在matalb中对于反三角函数进行符号积分

Answer 1

--- help for filtstates/int.m ---

INT Convert a FILTSTATES.CIC object to an integer matrix.

INT(Hs) returns an signed integer matrix for the FILTSTATES.CIC

object.

EXAMPLE:

Hm = mfilt.cicdecim;

hs = Hm.states; % Returns a FILTSTATES.CIC object

states = int(hs); % Convert object to a signed integer matrix.

int（***）：就是把括号里的转化成整型类型.

int(x*asin(1/x^2)*log(x^4),x = 1..3)：该函数得到结果后,把结果变成整型,如果计算得到3.5,那么输出的是3
