How to put your own data into the GUI created from the "GUIDE App Containing Tables and Plots" example given by MathWorks?

I am trying to insert four columns of data that represent the output from a DAC in voltage,decimal,binary, and hexadecimal forms/base. I want to simply replace the data given in the example with my data but when i do that I get an error saying "not enough input arguements." I am not certain how thats the case considering I actually have more inputs. (note: the given example input in a 288x2 double and I replaced that with my input which is a 100x4 cell)

Here is the code for my data:

clear all; clc;

decArr = [128,136,143,151,159,167,174,182,189,196, ...

202,209,215,220,226,231,235,239,243,246, ...

249,251,253,254,255,255,255,254,253,251, ...

249,246,243,239,235,231,226,220,215,209, ...

202,196,189,182,174,167,159,151,143,136, ...

128,119,112,104,96,88,81,73,66,59,53,46, ...

40,35,29,24,20,16,12,9,6,4,2,1,0,0,0,1,2, ...

4,6,9,12,16,20,24,29,35,40,46,53,59,66,73, ...

81,88,96,104,112,119];

x = decArr'; %decimal

y = round((x * (.019607843)),2);

%plot(x)

hexD = dec2hex(x);

binA = dec2bin(x);

m = strcat(string(binA(:,1:4)),string(" "),string(binA(:,5:8)));

Voltage = pad(strip(string(y)),'both');

Decimal = pad(strip(string(x)),'both');

Binary = strip(m);

Hexadecimal = strip(string(hexD));

vv = cellstr(Voltage);

xx = cellstr(Decimal);

yy = cellstr(Binary);

zz = cellstr(Hexadecimal);

Any advice would be great!
