MATLAB Coderのinterp1の外挿動作について
이전 댓글 표시
yq=interp1(x, y, xq, 'linear', 'extrap') を Coder でビルドしようとすると'extrap' のある影響でエラーになります。 MATLAB 本体ではcharでもdoubleでも受け付ける項目のためかと存じます。 Coder に対しどのように設定すれば動作しますでしょうか。 現状 char 1 x :inf で設定してます。 また、上記エラーが出ると MATLAB 全体がフリーズして PC をシャットダウンするかかなり長時間待ってからMATLABを強制終了しないと復帰しません。

Approximate translation:
Attempting to build yq = interp1 (x, y, xq, 'linear', 'extrap') with Coder causes an error due to some influence of 'extrap'. In MATLAB itself, it is probably due to an item accepted by either char or double. How do I configure Coder to operate? It is currently set with char 1 x: inf. Also, if the above error occurs, MATLAB entirely freezes to shut down the PC or wait for quite a long time before returning unless MATLAB is forcibly terminated.

In R2017a, on OS-X, I had no problems with extrap with code generation:
function yq = testinterp
x = 1:20;
y = sin(x*pi/7);
xq = linspace(0,30,20);
yq = interp1(x, y, xq, 'linear', 'extrap');
