How do I find for a particular element in a multidimensional array?

I have a 4 dimensional array and I would like to find a number in it and also find its position in the array. I cannot use the FIND command directly on an array which has more than 2 dimensions.

There is no direct function to achieve this functionality. Following example will accomplish it.

t = rand(10,10,10,10);

%assign the number that needs to be found in the array to ToBeFoundOut 

ToBeFoundOut = t(1,1,1,6)

index = find(t(:) == ToBeFoundOut )

%The dimensions of the array needs to be fed as an input to ind2sub function

s = [ 10,10,10,10];

[I,J,K,L] = ind2sub(s,index)
