XYZCreateFromMatrixΒΆ
XYZCreateFromMatrix creates a 3D dataset.
-
hData = XYZCreateFromMatrix(ssName, rmZ, rvRange)
Return Value
hData is the handle of the dataset. If the dataset cannot be created hData is 0.
Parameters
-
ssName ssName is a scalar string.
-
rmZ rmZ is a matrix with z-values.
-
rvRange rvRange is a vector with 4 elements that set the range of the z-matrix on the xy-plane. rvRange is built as the following: rvRange = [rsXmin, rsYmin, rsXmax, rsYmax]. rsXmin must be smaller than rsXmax and rsYmin must be smaller as rsYmax.
Comment
The matrix must have a minimum of 2 * 2 elements. The matrix does not have to
be square.
See also XYZCreate if the matrix is measured at certain x- and y-coordinates.
Example
Copy the following example into an UniPlot Editor (File=>New
[Program Editor]) and choose UniScript=>Save/Execute to execute the
script.
x = linspace(-10, 6.0, 30);
y = linspace(-10, 5.0, 30);
<xx, yy> = meshdom(x,y);
zz = sin(sqrt(xx.*xx + yy.*yy)) + sin(xx);
rvRange = [x[1], y[1], x[len(x)], y[len(y)]];
hData = XYZCreateFromMatrix("sin", zz, rvRange);
hLayer = LayerCreate();
hDoc = DocCreate();
hPage = PageCreate();
DocAddPage(hDoc, hPage);
PageAddLayer(hPage, hLayer);
LayerAddDataset(hLayer, hData);
LayerAutoScale(hLayer);
PageReplot(hPage);
