How do you find the index of a max value in a matrix in Matlab?
How do you find the index of a max value in a matrix in Matlab?
In case of a 2D array (matrix), you can use: [val, idx] = max(A, [], 2); The idx part will contain the column number of containing the max element of each row. You can use max() to get the max value.
How do you find the index of a matrix in Matlab?
Description. k = find( X ) returns a vector containing the linear indices of each nonzero element in array X . If X is a vector, then find returns a vector with the same orientation as X . 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.
- If A is a vector, then max(A) returns the maximum of A .
- If A is a matrix, then max(A) is a row vector containing the maximum value of each column.
What is the index of a matrix?
An index matrix is a matrix with exactly one non-zero entry per row. Index matrices are useful for mapping observations to unique covariate values, for example.
How do I find the maximum value in MATLAB?
In order to find the maximum value, you need to employ some MATLAB functions (max and find). MaxVelocity = max(Y) This will imply the peak value of your velocity profile. So far you just know the max value. But if you want to find corresponding time value for max velocity, first you need to find index of it.
How do you calculate the minimum of a function?
To find the minimum or maximum value of a function, perform the following steps: Graph the function in a viewing window that contains the minimum and/or maximum values of the function. Set the Format menu to ExprOn and CoordOn. Press [2nd][TRACE] to access the Calculate menu. Press [3] to find the minimum, or press [4] to find the maximum.
What is the maximum value of a quadratic function?
The quadratic function f(x) has a maximum value if a is negative. The quadratic function f(x) has a maximum value when (x + p) = 0. The maximum value is equal to q. Hence the maximum point is (-p, q)
