How do I find the first instance of a value in MATLAB?

How to find first instance of a value in array?

  1. arr(p)=abs(c); «solute value of c.
  2. if(arr(p)<1)
  3. if(arr(p)>0.9)
  4. array(t)=white1;
  5. cor(t)=arr(p); %correlation for c>.95 && c<1.
  6. t=t+1;
  7. end.
  8. end.

What does the Find function do in MATLAB?

find (MATLAB Functions) k = find(X) returns the indices of the array X that point to nonzero elements. If none is found, find returns an empty matrix. [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X .

How do I find a specific value in an array in MATLAB?

Direct link to this answer

  1. You can use the “find” function to return the positions corresponding to an array element value. For example:
  2. To get the row and column indices separately, use:
  3. If you only need the position of one occurrence, you could use the syntax “find(a==8,1)”.

How do you find the index of a specific value in MATLAB?

k = find( X ) returns a vector containing the linear indices of each nonzero element in array X .

  1. If X is a vector, then find returns a vector with the same orientation as X .
  2. If X is a multidimensional array, then find returns a column vector of the linear indices of the result.

How do you find the max value in MATLAB?

M = max( A ) returns the maximum elements of an array.

  1. If A is a vector, then max(A) returns the maximum of A .
  2. If A is a matrix, then max(A) is a row vector containing the maximum value of each column of A .

Which one of these does the Find function return MATLAB?

[i,j] = find(…) returns the row and column indices of the nonzero entries in the matrix X . This syntax is especially useful when working with sparse matrices.

How do you find a number in a matrix?

The number of elements of a matrix = the number of rows multiplied by the number of columns. For example, if the number of rows is 3 and the number of columns is 4 in a matrix then the number of elements in it is 3 x 4 = 12.

How do you find the value of an element in a matrix?
