I'm using poly11 to fit some data and keep getting this error

Error using fit>iFit (line 269)

Insufficient data.

You need at least 2 data points to fit this model.

Do you know what causes this? Thanks. The array is called data and when I check its dimensions, it seems as if there is enough data.

[nx ny] = size(data)

nx =

ny =

32768

What casuses this?
