我怎么才能将矩阵中的NaN去掉 用matlab?我的矩阵是这样的[ 1,2,nan,nan,3,nan1,2,nan,nan,3,nan1,2,nan,nan,3,nan1,2,nan,nan,3,nan]
matlab线性回归问题A=[1 1 1 2;1 0 0 0;1 1 2 3]X=A(:,1:3);Y=A(:,4);[b,bint,r,rint,stats] = regress(Y,X)A =1 1 1 21 0 0 01 1 2 3b =-0.00001.00001.0000bint =NaN NaNNaN NaNNaN NaNr =1.0e-015 *0.88820.12810rint =NaN NaNNaN NaNNaN NaNstats =1 NaN NaN
已知数列{an}满足a1=1/3,a2=7/9,an+2=4/3an+1-1/3an (1)求{an}的通项公式 (2)求数列{nan}的前n项和Sn第(2)问哪个{nan}的n打错了吗?nan前n项和无法求解呀,
an>0,{nan}有界,证明级数an收敛
nan是什么意思
英文单词‘nan
英语啊nan nan 我
怎样用matlab求((a^x+b^x+c^x)/3)^(1/x)在x趋近于0时的极限?为啥结果是NaN?
求数列a,2a2,3a3,4a4,…,nan,…(a为常数)的前n项和.若a=0,则Sn=0 若a=1,则Sn=1+2+3+…+n= 若a≠0且a≠1 则Sn=a+2a2+3a3+4a4+…+ nan ∴aSn= a2+2 a3+3 a4+…+nan+1 ∴(1-a) Sn=a+ a2+ a3+…+an- nan+1 = ∴Sn= 看不懂
如何将matlab矩阵中的NaN替换成0我用的是matlab7.6 再将一些数据导入到matlab后发现有好多的NaN,如何将这些NaN换成0呢?
matlab中计算结果出现NAN是什么意思a=[1 -1 -2 -1;2 1 1 1;1 1 0 -3;0 1 -1 -7],b=[0;0;0;0],c=aa = 1 -1 -2 -1 2 1 1 1 1 1 0 -3 0 1 -1 -7b = 0 0 0 0Warning: Matrix is
已知函数f(x)=m*2^x+t的图像经过点A(0,0),B,(3,7)及C(n,Sn),Sn为数列an的前n项和(n属于N*)求Sn及an通项公式若数列cn满足cn=nan,求数列cn的前n项和Tn
极限的运算法则!已知 lim(2n+1)an=3,lim(nan)=
极限(nAn)=-2,极限(3n+1)An的值
数列An中,a1=3,nAn+1=(n+2)An,求通项an,
matlab NaN值处理原始数据如图.现在需要把图中每列的NAN值变成本列第一个成为非NAN值.比如第一列第一个数据处理成5.5,3-5行的NAN值变成7.3,第二列1:-4行的变成5.4,第四列1-4行的变成13.2886.求用for
MATLAB中NaN +
