In an assignment A(I) = B, the number of elements in B and I must be the same.

Hi Guys, first of all I am beginner in Matlab. I want to get Average Values of NDVI for each month during a year. I used this

i=1:12;
jan(i)=ndvi_avhrr_monthly_avg{i};

and then I got this Error (((In an assignment A(I) = B, the number of elements in B and I must be the same.))).

Thanks

Please format your code properly. I've fixed this for you today.

exactly the same question was asked a few minutes before :)

And possibly a million times before.

jan(i) is a scalar and obviously the contents of ndvi_avhrr_monthly_avg{i} is not a scalar. Therefore the right hand side cannot be assigned to the left hand side.

Hi Jan, so what can I do?

[Image Analyst]

ndvi_avhrr_monthly_avg{i} needs to be a single number to assign it to an element of an array like that. What does this say

cellContents = ndvi_avhrr_monthly_avg{i}
whos cellContents

It will be more than one element. For exmaple cellContents might be a 42 by 300 matrix. So which element do you want to take from cellContents and stuff into jan(i)? Or you can make a structure and just attach the whole array:

simon.theArray = cellContents;  % Transfer ALL of the elements.

Thank you so much Jan
