labkit.dta.getCurveXY

Description

Looks up two headers using case-sensitive, exact-name matching. Rows where either selected column is NaN are removed from both outputs so x and y remain paired. Use getColumn when case-insensitive lookup or unfiltered data is required.

Inputs

curve

Scalar parsed curve structure with headers and data fields.

xsel

Character vector or string scalar matching one header exactly.

ysel

Character vector or string scalar matching one header exactly.

Outputs

x

Numeric column vector for xsel, with paired NaN rows removed.

y

Numeric column vector for ysel, with paired NaN rows removed.

xname

Matched header character vector, or '' when lookup fails.

yname

Matched header character vector, or '' when lookup fails.

Failure Behavior

If either exact header is absent, all numeric outputs remain empty and unmatched names are ''. curve must expose corresponding headers and data fields; malformed structures raise the originating MATLAB error.

Typical Call
