I have a number in a matrix say 17 and I need to find this row number(17) in another matrix and find the corresponding value in that cell. How do I pull the corresponding value for the row from another matrix? 댓글 수: 1 ...
>>[m n] = find(a==b);这里[m n]返回的是满足条件的元素的行索引和列索引。如果矩阵a中没有元素等于max，find函数将返回一个空矩阵，如Empty matrix: 0-by-1。如果find函数返回Empty matrix: 0-by-1，则表示矩阵a中不存在与max相等的元素。这可能是由于以下几种原因：矩阵a中没有最大值。

That is, R=EA for invertible matrix E. Clearly, then, U=E^(-1)Now, because of the way matrix multiplication works, if you augment A with the identity matrix and row-reduce, you'll transform [A\ |\ I] into [EA∣ EI]=[R\ |E]. So, one way to find U is to augment A with...
So i am asked to get all the cases where a projected distance is between 9.0 and 11.0 m in a matrix with about 36000 entires. i did this using the find function like this a = find((S_model>9.0)&(S_model<11.0)); S_model is the matrix name and n...
void InputMatrix(int *p, int m, int n); int FindMax(int *p, int m, int n, int *pRow, int *pCol); int main() { int a[M][N], m, n, row, col, max; printf("Input m,n:"); scanf("%d,%d", &m, &n); InputMatrix(*a, m, n); ...
I want to find which column gets the maximum value from first raw elements and which column gets the maximum value from 2nd raw values. I know I can derive maximum value from this max(A(1, :)) . But I can´t find it´s column number. Thank you in advance. ...
Discern the vowels and consonants in the word by finding the points at which the variance of the signal changes significantly. Limit the number of changepoints to five. Get numc = 5; [q,r] = findchangepts(mtlb,Statistic="rms",MaxNumChanges=numc); Create a signal mask for the speech ...
