Reconstruct a compressed vector based on another one with equal space entities

Hi,

assuming I have a Vector of Values and a corresponding Position Vector with constant steps of 250:

VaVector(1,20,-4,23,NaN,NaN,NaN,6,3,NaN,7,-23);

PosVector(2000,2250,2500,2750,3000,3250,3500,3750,4000,4250,4500,4750);

However I have the compressed Vectors with deleted NAN, so I have

VaVector_comp(1,20,-4,23,6,3,7,-23);

PosVector_comp(2000,2250,2500,2750,3750,4000,4500,4750);

How can I reconstruct the VaVector & PosVector? Please note, my example here contains only 12 Values, for simplification (my real compressed Vector contains >5000)

Thank you

Chris

VC = [1,20,-4,23,6,3,7,-23]

VC = 1×8

1 20 -4 23 6 3 7 -23

PC = [2000,2250,2500,2750,3750,4000,4500,4750]

PC = 1×8

2000 2250 2500 2750 3750 4000 4500 4750

PV = PC(1):250:PC(end)

PV = 1×12

2000 2250 2500 2750 3000 3250 3500 3750 4000 4250 4500 4750

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

VV = nan(1,numel(PV));
VV(ismember(PV,PC)) = VC

VV = 1×12

1 20 -4 23 NaN NaN NaN 6 3 NaN 7 -23
