isrow

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)
