Error using table (line 253) All variables must have the same number of rows.

i don't know why there's an error with my table. all varibales have 25 values.

here's my code

step= (0.0:0.2:5)';
Psi0= psiO(:,1)';
Psi1= psiO(:,6)';
Psi2= psiO(:,11)';
Psi3= psiO(:,16)';
Psi4= psiO(:,21)';
Psi5= psiO(:,26)';
table(step,Psi0,Psi1,Psi2,Psi3,Psi4,Psi5)

You might want to try to fix your code with the help of: Debug a MATLAB Program and Examine Values While Debugging

i examined all my values in the table. They all have 25 values. i don't know what's wrong?!

[per isakson]

step= (0.0:0.2:5)';
>> length( step )
ans =
    26

The first input is a column and rest are rows..so the error. Try:

table(step,Psi0',Psi1',Psi2',Psi3',Psi4',Psi5')

You need to rethink on your code. The initilaization and calling th eindices is not good.

[Ali Mulhi]

step= (x)';

Psi0= psiO(:,1);

Psi1= psiO(:,6);

Psi2= psiO(:,11);

Psi3= psiO(:,16);

Psi4= psiO(:,21);

Psi5= psiO(:,26);

table(step,Psi0,Psi1,Psi2,Psi3,Psi4,Psi5)

It worked when i took off ( ' ) at the end of the (psi0,psi1,psi2,psi3,psi4,psi5). As if the variables were already coulme arranged so there's no need to use ( ' ). though this is strange!

[KSSV]

It is not strange.......either you should input all rows or columns.....in my case I used all columns.

YOu have transposed the first input to a row from columna nd rest all are rows....

[Ali Mulhi]

I got it. Thanks Sir!

[Peter Perkins]

Psi0 = array2table(psi0(:,[1 6 11 16 21 16])

would have been helpful for this. And then addvars to add step at the beginning.

[Guillaume]

or

[table(step), array2table(psi0(:,[1 6 11 16 21 16]))]

Either of these is a lot simpler than temporary numbered (!) variables.

Is there any difference between addvars and table concatenation?

[Peter Perkins]

addvars lets you add new variables in the middle. It's really the only reason why it even exists.
