how to use makeUniqueStrings

c=num2cell((1:10)')

c = 10×1 cell array
    {[ 1]}
    {[ 2]}
    {[ 3]}
    {[ 4]}
    {[ 5]}
    {[ 6]}
    {[ 7]}
    {[ 8]}
    {[ 9]}
    {[10]}

matlab.lang.makeUniqueStrings(c)

Error using matlab.lang.makeUniqueStrings
First argument must be a string array, character vector, or cell array of character vectors.

The error clearly states what the expected input is.

What exactly are you trying to do? What is the objective?

I want to change the name of the double numbers

i see, but how can i convert cell number in cell string?

c=num2cell([[1:10],[4:10]])

c = 1×17 cell array
    {[1]}    {[2]}    {[3]}    {[4]}    {[5]}    {[6]}    {[7]}    {[8]}    {[9]}    {[10]}    {[4]}    {[5]}    {[6]}    {[7]}    {[8]}    {[9]}    {[10]}

Use string on the numbers, no need to convert them to a cell.

"I want to change the name of the double numbers"

What do you mean by this?

cc=string([[1:10],[4:10]])

cc = 1×17 string array
    "1"    "2"    "3"    "4"    "5"    "6"    "7"    "8"    "9"    "10"    "4"    "5"    "6"    "7"    "8"    "9"    "10"

matlab.lang.makeUniqueStrings(cc)

ans = 1×17 string array
    "1"    "2"    "3"    "4"    "5"    "6"    "7"    "8"    "9"    "10"    "4_1"    "5_1"    "6_1"    "7_1"    "8_1"    "9_1"    "10_1"

%now it's ok!
But if i want to change _1 with A? example : 4_1 ===> A4 ..How can i do it replace the _n with Alhpabetic letter?

Utilize the functionality of strings -

vec1 = 1:10;
vec2 = 4:10;

[vec1 "A"+vec2]

ans = 1×17 string array
    "1"    "2"    "3"    "4"    "5"    "6"    "7"    "8"    "9"    "10"    "A4"    "A5"    "A6"    "A7"    "A8"    "A9"    "A10"
