**Syntax**

**Description**

```
B = sortrows(A)
```

sorts the rows of `A`

as a group in ascending order. Argument `A`

must be either a matrix or a column vector.

For strings, this is the familiar dictionary sort. When `A`

is complex, the elements are sorted by magnitude, and, where magnitudes are equal, further sorted by phase angle on the interval .

```
B = sortrows(A,column)
```

sorts the matrix based on the columns specified in the vector `column`

. For example, `sortrows(A,[2 3])`

sorts the rows of `A`

by the second column, and where these are equal, further sorts by the third column.

```
[B,index] = sortrows(A)
```

also returns an index vector `index`

.

If `A`

is a column vector, then `B = A(index)`

.

If `A`

is an `m`

-by-`n`

matrix, then `B = A(index,:)`

.

**Examples**

Given the 5-by-5 string matrix,

The commands B = sortrows(A) and C = sortrows(A,1) yield
