How do you find the maximum and minimum of an array in Matlab?
How do you find the maximum and minimum of an array 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.
How do you find the minimum value in an array in Matlab?
M = min( A ) returns the minimum elements of an array.
- If A is a vector, then min(A) returns the minimum of A .
- If A is a matrix, then min(A) is a row vector containing the minimum value of each column.
How do you use the MIN MAX function in Matlab?
How to use the min() and max() functions? According to the Mathworks website, using minVal = min(FHNout); and maxVal = max(FHNout); should work.
How do you find the max value of an array?
To find the maximum value in an array:
- Assign the first (or any) array element to the variable that will hold the maximum value.
- Loop through the remaining array elements, starting at the second element (subscript 1). When a larger value is found, that becomes the new maximum.
How do you find the max position in Matlab?
[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. The max function can also return the index of the maximum value in the vector.
How do you find the max value on a graph in Matlab?
All you need to do is use the max() function. The max() function will return both the maximum value, and the index position of the value. You can use the index to extract the corresponding a1. The ‘ro’ option tells matlab to plot (a1_max, b1_max) in red, and using an ‘o’ as marker.
How do you find the average of an array in Matlab?
M = mean( A ) returns the mean of the elements of A along the first array dimension whose size does not equal 1.
- If A is a vector, then mean(A) returns the mean of the elements.
- If A is a matrix, then mean(A) returns a row vector containing the mean of each column.
How do you find the max point on a graph in Matlab?
How to get the maximum value of a column in MATLAB?
Accepted Answer. The “min” and “max” functions in MATLAB return the index of the minimum and maximum values, respectively, as an optional second output argument. 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.
How to find the minimum and Max of a multidimensional array?
Function to calculate the minimum value and its indices, in a multidimensional array – In order to find the max, just replace the min (array (:)) statement with max (array (:)). % First of all, identify the Matlab convention for numbering the elements of a multi-dimensional array.
How do you find the minimum of an array in Matplotlib?
M = min(A) returns the minimum elements of an array. If A is a vector, then min(A) returns the minimum of A. If A is a matrix, then min(A) is a row vector containing the minimum value of each column. If A is a multidimensional array, then min(A) operates along the first array dimension whose size does not equal 1, treating the elements as vectors.
How do you find the maximum value of an empty array?
If A is an empty array whose first dimension has zero length, then max (A) returns an empty array with the same size as A. M = max (A, [],dim) returns the maximum element along dimension dim. For example, if A is a matrix, then max (A, [],2) is a column vector containing the maximum value of each row.
