How do you use the sort function in Matlab?

How do you use the sort function in Matlab?

B = sort( A ) sorts the elements of A in ascending order.

1. If A is a vector, then sort(A) sorts the vector elements.
2. If A is a matrix, then sort(A) treats the columns of A as vectors and sorts each column.

How do you sort a data set in Matlab?

Sort Observations in Dataset Arrays

1. load hospital dsAgeUp = sortrows(hospital,’Age’); dsAgeUp(1:10,{‘LastName’,’Age’})
2. dsAgeDown = sortrows(hospital,’Age’,’descend’); dsAgeDown(1:10,{‘LastName’,’Age’})
3. dsName = sortrows(hospital,{‘Age’,’LastName’}); dsName(1:10,{‘LastName’,’Age’})

How do I sum a row in Matlab?

S = sum( A , ‘all’ ) computes the sum of all elements of A . This syntax is valid for MATLAB® versions R2018b and later. S = sum( A , dim ) returns the sum along dimension dim . For example, if A is a matrix, then sum(A,2) is a column vector containing the sum of each row.

How do you use the MAX function in Matlab?

C = max( A , B ) returns an array with the largest elements taken from A or B ….M = max( A ) returns the maximum elements of an array.

1. If A is a vector, then max(A) returns the maximum of A .
2. If A is a matrix, then max(A) is a row vector containing the maximum value of each column of A .

How do you use mods in Matlab?

b = mod( a , m ) returns the remainder after division of a by m , where a is the dividend and m is the divisor. This function is often called the modulo operation, which can be expressed as b = a – m. *floor(a./m) . The mod function follows the convention that mod(a,0) returns a .

How do you sort a cell array in Matlab?

You can convert your cell array into a matrix using CELL2MAT, sort according to the column you choose using SORTROWS, and then convert the matrix back to a cell array using MAT2CELL. Note that there are certain limitations on the cell array for being able to use the CELL2MAT function.

How do you find the mean of a matrix in Matlab?

M = mean( A ) returns the mean of the elements of A along the first array dimension whose size does not equal 1.

1. If A is a vector, then mean(A) returns the mean of the elements.
2. If A is a matrix, then mean(A) returns a row vector containing the mean of each column.

How do I sort a DataFrame in R?

To sort a data frame in R, use the order( ) function. By default, sorting is ASCENDING. Prepend the sorting variable by a minus sign to indicate DESCENDING order.
