Sounds to me as if you have accidentally created a variable named "plot".
In the mean time, use round() on your data and see if you get a plot out. My guess is that you will not.

What is "a" ? If it is an array, then a(z) would be attempting to subscript "a" by the values in "z".
If "a" is an array and you are expecting that "z" will work out as integral, then you might be experiencing floating point roundoff limitations; if so then a(round(z)) should work (unless some z rounds to zero.)

Hi,
have a look at the format function:

So this should work
format long

No it's not stopping you unless the variable is a string instead of a number, please provide more details.

i guess the 'e' in the number must be interpreted as a character by matlab which is why its giving me an error while plotting.
