Make arrays into a table

Hi,

I have 6 arrays of equal length, each representing a certain parameter and each slot in the array represents the value of the parameters

I would like to tabulate the data so that I can scroll through and see all the data at once. How may I do this?

The image below is what I am looking for, ideally where I can specify a label in the left most column.

It's better to organize the table in transposed order.

a1 = rand(10, 1);
a2 = rand(10, 1);
a3 = rand(10, 1);
T = table(a1, a2, a3)

T = 10×3 table
       a1         a2          a3

plot(T.a1)

Ohh wow, it is that easy, thank you! It doesn't make a huge amount of difference to me, but say if I wanted to plot the table in the orientation I showed in my original post, how may I go about this?

[Chunru]

use plot(T.a1), for example.

I've just tried your solution with my arrays and It just shows me the headings an says "1x12 double" instead of listing the 12 data points.

[Chunru]

In that case, you may need to transpose your data first before forming the table. See the size of the variables a, b, c.

TOK, you have 6 series, each with length 10. The normal way to orient that would be 10 rows, 6 columns. Nonetheless,

>> a1 = rand(1,10);
>> a2 = rand(1,10);
>> a3 = rand(1,10);
>> T = array2table([a1;a2;a3])
T =
3×10 table
Var1        Var2       Var3        Var4        Var5       Var6       Var7       Var8       Var9       Var10  
_______    ________    _______    ________    ________    _______    _______    _______    _______    ________
0.70605    0.031833    0.27692    0.046171    0.097132    0.82346    0.69483     0.3171    0.95022    0.034446
0.43874     0.38156    0.76552      0.7952     0.18687    0.48976    0.44559    0.64631    0.70936     0.75469
0.27603      0.6797     0.6551     0.16261       0.119    0.49836    0.95974    0.34039    0.58527     0.22381

But if you want to plot each series as one line, that's the wrong orientation to use, as Chunru showed..
