帮忙解释下这两条Matlab命令1.>>int2str(eye(3))ans=1 0 00 1 00 0 1size(ans)为啥是 3 2.关于eval函数的>> funs=char('ceil','fix','floor','round')funs =ceil fix floorround>> [deblank(funs(1,:)) '(pi)']ans =ceil(pi)>> f=eval([deblank(funs(
matlab M=ceil(3.32*pi/dw);N=2*M+1;n=-M:
Size
log2 SQR(7/48)+log2 12 -1/2log2 42
log2 SQR(7/48)+log2 12 -1/2log2 48
log2^(4^7*2^5)+log2^6-log2^3
(log2 9)/(log2 8) = 2/3(log2 3)
log2 3乘以log2 3等于2log2
(log2)^2+(log5)^2+log2*log25
|[log2(x)]^2-3log2(x)+1|
化简:(log2(x/4))*(log2(x/2))
2log2 10—log2 25=?
(log2)2+log2*log50+1g25值
log2 50-2log2 5 等于多少?
[log2]2+log2乘log50+log25
matlab中的size(A,2)==size(B,
