## Repeated Values (Scripts) Publisher's description

### REPVAL Repeated Valuesrepval(X) finds all repeated values for input X, and their attributes.

REPVAL Repeated Values
repval(X) finds all repeated values for input X, and their attributes.
The input may be vector, matrix, char string, or cell of strings

Y=repval(X) returns the repeated values of X

[RV, NR, POS, IR]=repval(X) returns the following outputs
RV : Repeated Values (sorted)
NR : Number of times each RV was repeated
POS : Position vector of X of RV entries
IR : Index of repetition

Example:
X=[1 5 5 9 5 5 1];
[RV,NR,POS,IR]=repval(X)

Output:
RV = [1 5]; %Numbers '1' and '5' are repeated values
NR = [2 4]; %Respectively repeated 2 and 4 times
POS = [1 7 2 3 5 6]; %Position index of X for repeated values
IR = [1 1 2 2 2 2]; %Corresponding to which index of RV

Vectors
[RV,NR,POS,IR]=repval([1 2 2 3 2 2 1])

Matrix (repeated rows)
[RV,NR,POS,IR]=repval([1 2; 3 4; 1 2; 1 3; 3 4])

Char String

Cell of Strings
[RV,NR,POS,IR]=repval({'bat','cat','car','bar','bat','car'})
