Wanting to call a number from a 1x6 double

In my code Im calculating inverse kinematics where:

J = bot.ikine(T, [0 0 0], [1 1 1 1 1 0 0 0]) *180/pi

In the workspace J is labelled as a 1x6 double

and in the command window J outputs 6 different number like so:

J =
9.4623  -71.4600  -21.3836    0.0000  -50.0763   -9.4623

Im trying to print the seperate values on a GUI so for example Theta 1 will display 9.4623, theta 2 will display -71.4600 etc ...

However when I try to select a number from J:

J(1,6)

this displays -9.4623 when I throught it would display 9.4623

also when i then try to select the second number from J:

J(2,6)

I get the following error

Index in position 1 exceeds array bounds (must not exceed 1).

Does anyone have an idea how i can reference to each number within J?

"However when I try to select a number... J(1,6)... this displays -9.4623 when I throught it would display 9.4623"

The sixth value in the first row is -9.4623. You did not explain why you think it should be something else.

"also when i then try to select the second number ...J(2,6) ... I get the following error "

The array J has only one row: what do you expect to occur when you try to access an element from a row that does not exist?

"Does anyone have an idea how i can reference to each number within J?"

Because your data are in a vector, linear indexing is sufficient, e.g.:

J(2)
J(6)

Your array has the size 1x6. So it contains values at the positions (1,1) = 9.4623, (1,2) = -71.4600, (1,3) = -21.3836 and so on.

You can either try J(1,1), J(1,2) ... to get your 6 values or J(1), J(2) will also work.

Thank you this has solved the problem!
