ind2sub - linear index to matrix subscript values

Calling Sequence

[i1,i2,..] =ind2sub(dims,I)

Mi = ind2sub(dims,I)

Parameters

• dims : vector: the matrix dimensions
• I : vector: the given linear index
• i1,i2,.. : the subscript values (same matrix shape as I )
• Mi : matrix whose columns contains the subscript values.

Description

ind2sub is used to determine the equivalent subscript values corresponding to a given single index into an array. [i1,i2,..] = ind2sub(dims,I) returns the arrays i1 , i2 , ... containing the equivalent row, column, ... subscripts corresponding to the index matrix I for a matrix of size dims . Mi=ind2sub(dims,I) returns a matrix Mi whose columns are the arrays i1(:) , i2(:) , ...

Examples

   ind2sub([2,3,2],1:12)
   [i,j,k]=ind2sub([2,3,2],1:12)
