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?

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.
