How do you find the index of minimum value in MATLAB?
M = min( A ,[], dim ) returns the minimum element along dimension dim . For example, if A is a matrix, then min(A,[],2) is a column vector containing the minimum value of each row.
How do you find the minimum value of an index?
Index of minimum value using min() and index() Python functions. The python has a built-in function of min() which returns the minimum value in the list and index() which returns the index of the element. These two functions can be used to find the index of a minimum element in a single line code.
How do you find the maximum value index in MATLAB?
You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable. Here, 7 is the largest number at the 4th position(index).
How do you find the maximum value of an index?
index() functions to find out the index of the maximum value in a list. Use the enumerate() function to find out the index of the maximum value in a list. Use the numpy. argmax() function of the NumPy library to find out the index of the maximum value in a list.
How do you find the minimum value index of an array?
To get the index of the min value in an array:
- Get the min value in the array, using the Math. min() method.
- Call the indexOf() method on the array, passing it the min value.
- The indexOf method returns the index of the first occurrence of the value in the array or -1 if the value is not found.
How do you find the index of a matrix in MATLAB?
In logical indexing, you use a single, logical array for the matrix subscript. MATLAB extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column vector. For example, A(A > 12) extracts all the elements of A that are greater than 12.
How do I find a specific value in an array in MATLAB?
Direct link to this answer
- You can use the “find” function to return the positions corresponding to an array element value. For example:
- To get the row and column indices separately, use:
- 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 matrix?
Let A be an n×n complex matrix. The smallest nonnegative integer k such that rank(Ak+1)=rank(Ak), is the index fo A and denoted by Ind(A).
How do you find the index of an array?
To find the position of an element in an array, you use the indexOf() method. This method returns the index of the first occurrence the element that you want to find, or -1 if the element is not found.
