Matlab Common small function

Sum: Sum operation

Sum (a): Matrix A sums by column (sum of each column), resulting in a row vector

SUM (a,2): Matrix A sums by rows (sums each row), resulting in a row-and-column vector

Max: Max element operation

Returns only the maximum value condition

Max (a): matrix A maximizes the value by column (maximum of each column) and results in a row vector

Max (a,[],2): matrix A maximizes the value by row (maximum of each row) and results in a single column vector

Max (the maximum value in a (:)) matrix A

Returns the maximum value and the location of the condition

[M,i] = max (a): Returns the indicator and maximum of the maximum value of each column in matrix A, M and I are a row vector, I hold the maximum number of rows for each column in a, and m holds the maximum value for each column in a

[M,i] = max (a,[],2): Returns the metric and maximum of the maximum value for each row in matrix A, M and I are a column vector, I hold the maximum number of columns for each row in a, and m holds the maximum value for each row in a

[M,i] =max (A (:)): Returns the index and maximum of the maximum value in matrix A, M and I are a number, I is the index of the largest value in a, M is the maximum value in a
