If I have
A1 =
1.0e-013 *
Columns 1 through 8
0.1481 0.1574 0.1465 0.1481 0.1574 0.1465 0.1481 0.1574
Column 9
0.1465
And
A2 =
1.0e-013 *
Columns 1 through 8
0.1250 0.1523 0.1465 0.1250 0.1523 0.1465 0.1250 0.1523
Column 9
0.1465
How can I plot either variables, on the same bar plot?
bar([A1 A2])
legend('A1,'A2')
If MATLAB said:
Warning: Ignoring extra legend entries.
> In legend at 278
What's the mistake?

A1 =1.0e-013 *[ 0.1481 0.1574 0.1465 0.1481 0.1574 0.1465 0.1481 0.1574]
A2= 1.0e-013 *[0.1250 0.1523 0.1465 0.1250 0.1523 0.1465 0.1250 0.1523]
bar([A1' A2'])
legend('A1','A2')

If there are so many elements in A1 and A2 and, a priori, I don't Know how many elements, how can I do it?

What do you mean by so many element? give an example

The A1 and A2 variables are define before in the code. In this case A1 is 1x9 double and also A2. But it may be 1xn double for A1 and A2. If A1=A2=1xn, I can't do as you said because I have not entire into the code.

(I have not entire into the code): This sentence is not clear for me

But If I have A1 and A2 variables, for example, A1=A2=1*n how I can do the bar plot?

The same as the above answer
bar([A1' A2'])
legend('A1','A2')
