I am trying to create a table but somehow can't.

>> u = 100;
a = -9.81;
angle = 10;
angle = angle*pi/180;
ux = u*cos(angle);
uy = u*sin(angle);
tmax = -2*uy/a;
t = linspace(0,tmax,200);
vx = ux;
sx = ux*t;
sy = uy * t + 0.5*a*t.^2;
LastName = {'1:200'};
Time = [t];
Sx = [sx];
Sy = [sy];
T = table (Time,Sx,Sy,...'RowNames',LastName);

Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.

[Sara]

At what line is the error? Works just fine for me once 'RowNames',LastName); is put on a different line

[Adam]

how to put it on a different line?tried pressing enter, didn't help.sorry for the stupid question but i am just a begginner in matlab.

Answer 1

[Azzi Abdelmalek]

What those 3 dots are doing?

T = table (Time,Sx,Sy,'RowNames',LastName);

[Adam]

i tried doing that but got this instead:

>> T = table (Time,Sx,Sy,'RowNames',LastName);

Undefined function 'table' for input arguments of type 'cell'.

There are a few problems. One is that ‘Time’, ‘Sx’, and ‘Sy’ need to be column vectors, and ‘LastName’ needs to be a cell array.

Change to these lines and it works (or at least creates your table correctly):

LastName = strsplit(sprintf('%3d\n',1:200));
LastName = LastName(2:201);
Time = t';
Sx = sx';
Sy = sy';
T = table (Time,Sx,Sy,...
    'RowNames',LastName);

EDIT — I’m using R2014b. There may be version differences.

[Adam]

i'm using an older version, R2014a. Tried your coding but didn't work. is there any other way that i can show the data?

[Star Strider]

What ‘didn’t work’ about it? When I ran it, it produced:

T = 

              Time        Sx        Sy   
             _______    ______    _______

      1            0         0          0
      2      0.01779     1.752    0.30737
      3      0.03558     3.504    0.61163
      4      0.05337    5.2559    0.91279
      5      0.07116    7.0079     1.2108
             ... etc. ... to row 200

I’m a bit mystified. In your Comment to Sean’s answer you mention R2013a that does not support table, and here you mention R2014a that should support it. If you have a license for R2013a, you should be able to download and install R2013b on that same license, at least as I understand it. Then you will have table.

In the absence of being able to use table, I would use a matrix or a cell array, whatever is most convenient for you and best meets your needs.

Answer 3

[Sean de Wolski]

Table was added in R2013b. If you're using an older release, tables won't work. If your company/university is current on maintenance, you can likely upgrade at no additional cost.

[Adam]

yup. i'm using an older release, R2013a.
