ind2sub

linear index to matrix subscript values

Calling Sequence

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

Arguments

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)
