ArrayReshape

ArrayReshape(list-of-values, list-of-dimension)

returns the list-of-values elements reshaped as nested list with dimensions according to the list-of-dimension.

ArrayReshape(list-of-values, list-of-dimension, expr)

Use expr to fill up elements, if there are too little elements in the list-of-values.

Examples

A list of non-negative integers is expected at position 2. The optional third argument x is used to fill up the structure:

>> ArrayReshape({a, b, c, d, e, f}, {2, 3, 3, 2}, x)
{{{{a,b},{c,d},{e,f}},{{x,x},{x,x},{x,x}},{{x,x},{x,x},{x,x}}},{{{x,x},{x,x},{x,x}},{{x,x},{x,x},{x,x}},{{x,x},{x,x},{x,x}}}}

Ignore unnecessary elements

>> ArrayReshape(Range(1000), {3, 2, 2})
{{{1,2},{3,4}},{{5,6},{7,8}},{{9,10},{11,12}}}
