The impulse response (that is, the output in response to a Kronecker delta input) of an Nth-order discrete-time FIR filter lasts exactly +1 samples (from first nonzero element through last nonzero element) before it then settles to zero. FIR filters can be discrete-time or continuous-time...
k=find(X,n,direction)(其中 direction 为 'last')查找与X中的非零元素对应的最后n个索引。direction的默认值为 'first',即查找与非零元素对应的前n个索引。 The last n index corresponding to the non-zero element in X. The default value of direction is 'first', which is to find the top n i...
for a 5-by-7-by-3 array X witha nonzero element at X(4,2,3), find returns4 in row and 16 in col. Thatis, (7 columns in page 1) + (7 columns in page 2) + (2 columns inpage 3) = 16.[row,col,v] = find(X, ...) returnsa column or row vector v of t...
In C, the first element of an mxArray has an index of 0. The jc array contains column index information. If the jth column of the sparse matrix has any nonzero elements, jc[j] is the index into ir and pa of the first nonzero element in the jth column. Index jc[j+1] - 1 ...
I want to find the first nonzero element in a matrix, I'm now using 테마복사 idx = find(NH3summer==min(NH3summer(NH3summer>0))); [E,B,M,P,U,L] = ind2sub(size(NH3summer),idx); NH3summer is a 6D matrix, but now i want to find...
2、b=find(a,2),找出a中最先出现的2个不为零的数,a是你所要找的矩阵,2参数是指数量；3、c=find(a,2,'first')，用法和上例基本一样；4、c=find(a,2,'last') 这句的意思是从最后一个非零元素起，找2个不为零的元素，如下图所示；5、[a1,a2]=find(a)，找出a矩阵中非零元素所在...
Find the nonzero elements in a 3-by-3 matrix. Specify three outputs to return the row subscripts, column subscripts, and element values. X = [3 2 0; -5 0 7; 0 0 1] 1. X =3×33 2 0 -5 0 7 0 0 1 1. 2. 3.
