# isrow

check if a variable is a row

## Calling Sequence

    t=isrow(x)

## Arguments

x

  scalar,vector, matrix, hypermatrix, list, array of structures or cells

t

  a boolean

## Description

`isrow(`x`)` returns true if `x` is a row. Scalars are considered as rows, and hypermatrix can be considered as rows only if all of its dimensions, except the last one, are equal to 1.

Note that `isrow([])` returns false.

## Examples

    isrow(ones(1,10))
    isrow(1)
    isrow(["s" "t" "u"])
    isrow(rand(1,1,3))
    isrow(rand(2,1,1))
    s = struct();
    isrow(s) // Empty structure
    clear s
    s.a = %z;
    s.b = 2;
    isrow(s) // Scalar array of structures
    clear s
    s(1,2).a = 3;
    s(1,3).b = %z;
    isrow(s) // Row array of structures
    clear s
    s(1,2).a = -2;
    s(3,1).b = %pi;
    isrow(s) // 2D array of structures
    clear s
    s(1,1,2).a = 3;
    s(1,1,3).b = "test";
    isrow(s) // 3D array of structures (with 2 singleton dims)
