Matlab return index of min how to#
Matlab return index of min code#

The sub2ind and ind2sub functions are useful in converting between subscripts and linear indices. The linear index changes depending on the size of the array A (5) returns a differently located element for a 3-by-3 matrix than it does for a 4-by-4 matrix. Why does the linear index change in MATLAB?

Matlab return index of min code#

For example, the following code produces a row vector ‘M’ that contains the maximum value of each column of ‘A’, which is 3 for the first column and 4 for the second column. The “min” and “max” functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. But argmax is something different ( en./wiki/Argmax ). He is using the name 'argmax' for it (and the made up function 'argmax (a)'). How do I find the indices of the minimum?Īccepted Answer. EvgeniSergeev does want to find the index of the max or min value in an array.

Matlab return index of min how to#

How to find the indices of MATLAB and Simulink? Matlab find indexes of x min values in column. An alternate solution using an inline function will work. get the index of minimum value matlab matlab index of max value matlab find. So to find the absolute index, you need to add “lowerBound” to the Index. This returns “Value” as the min or max value among A (lowerBound) and A (uppedBound) and “Index” as with “lowerBound” as the offset. How to get the index of the MIN VALUE in MATLAB? If you have the equation in the form of y = ax^2 + bx + c, then you can find the minimum value using the equation min = c – b^2/4a. You can find this minimum value by graphing the function or by using one of the two equations.

If your quadratic equation has a positive a term, it will also have a minimum value. thank you for your other choices, i will try them in future. min (a) 1 2 3 k,vmax (min (b)) output : k3 v3. How do you find the minimum of a function? thank you for your response, i used k,vmax (min (b)) where k gives the value and v gives the index. If A is a matrix, then max(A) is a row vector containing the maximum value of each column.If A is a vector, then max(A) returns the maximum of A.M = max( A ) returns the maximum elements of an array. How do you use the MAX function in Matlab? If X is a multidimensional array, then find returns a column vector of the linear indices of the result.If X is a vector, then find returns a vector with the same orientation as X.K = find( X ) returns a vector containing the linear indices of each nonzero element in array X.
