Subscripting into a table using three or more subscripts (as in t(i,j,k)) is not supported. Always specify a row subscript and a variable subscript, as in t(rows,vars).

Hi,

I am trying to create a joined table from 4 arrays (each has the same amount of elements), whay does this error means?

this is part of my code:

%turn table to int array

baseline = table2array(baseline);

retest1 = table2array(retest1);

retest2 = table2array(retest2);

retest3 = table2array(retest3);

%create a table for plotting

correct_sequences_table = table(baseline, retest1, retest2, retest3)

Error: Subscripting into a table using three or more subscripts (as in

t(i,j,k)) is not supported. Always specify a row subscript and a

variable subscript, as in t(rows,vars).

You accidentally created a variable named table that is a member of the object class named table . In the line that is having the problem, MATLAB thinks that you are trying to index the variable named table instead of trying to create a new table object.

thanks a lot!

sorry for this begginer's question :)

how could one fix this issue?

[Walter Roberson]

T = table;
clear table

Now the old value is in T and you can use table() as a function again.

Note that generally speaking the error about wrong number of subscripts indexing a table is often a slightly different problem than here. This analysis only holds for lines where it is complaining with that error on a line that appears to be creating a table. In cases where a different variable name appears, the problem is often trying to use just a row number to index a table, such as

T(5)

when you would need

T(5,:)

or a column reference as the second parameter, such as

T(5,'power_level')
T{5,3}

Lihi, hard to say for sure, but you may want to make a table that contains those four tables. For example:

>> baseline = table([1;2;3],[4;5;6],'VariableNames',["X" "Y"])
baseline =
  3×2 table
    X    Y
    _    _
    1    4
    2    5
    3    6
>> retest1 = table([7;8;9],[10;11;12],'VariableNames',["W" "Z"])
retest1 =
  3×2 table
    W    Z 
    _    __
    7    10
    8    11
    9    12
>> t = table(baseline,retest1)
t =
  3×2 table
    baseline    retest1
     X    Y     W    Z 
    ________    _______
     1    4     7    10
     2    5     8    11
     3    6     9    12
>> t.baseline.X
ans =
     1
     2
     3
