error in using array2table

I have two numerical values in an array x and two string values in an array y. In the workspace these are shown as [0, 7.2e-9] and 1X2 string. But when I try build a tavle using array2table as

array2table(x,'VariableNames', y);

I get the error

The VariableNames property must contain one name for each variable in the table.

What does this mean?

x = [0, 7.2e-9]

x = 1×2

1.0e-08 * 0 0.7200

y = ["hello","world"]

y = 1×2 string array
    "hello"    "world"

t = array2table(x, 'VariableNames',y)

t = 1×2 table
    hello     world 
    _____    _______

      0      7.2e-09

Is it a 1x2 string or 1x2 char?

@Dyuman Joshi: thank you for pointing out the wrong profile, now I can't figure out how to "@" the correct one :)

Hi @MAWE,

I was able to create a table successfully using the steps that you described:

x = [0, 7.2e-9];
y = ["var1", "var2"];
array2table(x,'VariableNames', y)

ans = 1×2 table
    var1     var2  
    ____    _______

     0      7.2e-09

I suspect that you were storing either "x" or "y" as a 2x1 array instead, which would trigger the error that you mentioned:

x = [0; 7.2e-9];
y = ["var1", "var2"];
array2table(x,'VariableNames', y)

Error using array2table
The VariableNames property must contain one name for each variable in the table.
