Find the index of the last numeric element of a column including NaNs

I have a column with many rows that has data in the middle surrounded by NaNs. For example, below is an abbreviated version of what I'm talking about. Let's call the column 'x':

NaN NaN NaN 235 6 24 NaN NaN

I am trying to find the index of 24 (the last numeric element in the column). So far I am able to do this:

find(~isnan(x))

The snippet above returns the index of all three numbers. I just want the last one (24). I have tried

find(~isnan(x(end)))

but this gives me an empty array (in the Workspace, the Value is []).

Can anyone shed some light on this. I appreciate everyone's help.

UPDATE: I have found the solution.

find(~isnan(x),1,'last')

Thanks for everyone's help.

find(~isnan(x),1,'last')

[Matt J]

To do this column-wise when x is a matrix, a slightly different approach is needed,

 [~,I]=max(flipud(~isnan(x)));

 result=size(x,1)+1-I;

find(~isnan(fliplr(x)),1)
