matlab Specific entries in a two dimensional array dataMatrix are identified by a logical index array logicalSelect$.$ Assign the first numSelected of the selected elements to an array selectedData.

Ex: If dataMatrix is $1-2,3,6$: $5,78,44$: $9,-3,-53],$ logicalSelect is $[1,0,0$: $0,0,1$: $1,1,1],$ and numSelected is $4,$ then selectedData is $[-2.$

$9$: $-3$: $44].$

function selectedData $-$ SelectLogicalN$($ dataMatrix, logicalSelect$,$ numSelected $)$

$\%$

SelectLogicaiN: Return the first numSelected values of input $20$ array dataMatrix indexed by localselect indexing array.

Inputs: dataMatrix $-$ input data matrix $(2$D array$)$

logicalSelect $-$ logical indexing array, can be $2$D on Linean numSelected $-$ number of indexed elements to return in selectedData

OutputS

SelectedData $-$ column vector of logically indexed elements to return

$\%$ Assign tempselected with logically indexed elements of dataMatrix tempSelected $-$ dataMatrix;

$\%$ Assign

selectedData with first numselected elements of tempselected

selectedData $=$ dataMatrix;
