[~,loc]=ismember(matrixName,value)
[i,j,k]=ind2sub([26,7,101],find(loc,1))
The above will find the first specified value in the matrix and return its i,j,k indices. The code would need some small modification if the value wasn't unique and you needed the indices of all occurrences of the specified value.

[i, j, k] = ind2sub( size(YourMatrix), find(YourMatrix == value, 1) );
remove the ", 1" if you want all of the occurrences.

Caution: you need to change strategy a bit if the values are floating point and the value you are looking for has not been directly copied out of the matrix.
