Description
Examples
Find the Size of a Mapshape Vector
Create a mapshape vector from a structArray
.
structArray = shaperead('worldrivers.shp');
ms = mapshape(structArray)
ms = 128x1 mapshape vector with properties: Collection properties: Geometry: 'line' Metadata: [1x1 struct] Vertex properties: (128 features concatenated with 127 delimiters) X: [126.7796 126.5321 126.3121 126.2383 126.0362 NaN NaN 126.0362 125.1356 124.7906 124.1364 123.7004 123.4859 123.2781 123.0678 NaN NaN -134.0218 -134.0882 -134.3638 -134.4989 -134.4732 -134.4100 NaN NaN -135.5902 -135.2130 ... ] (1x5542 double) Y: [73.4571 73.0669 72.8343 72.6010 72.2894 NaN NaN 72.2894 72.3784 72.4620 72.5086 72.5691 72.6517 72.8635 72.8684 NaN NaN 69.4726 69.3400 69.2873 69.1939 68.9479 68.8795 NaN NaN 68.9858 68.9367 68.9995 69.0016 68.8795 NaN NaN ... ] (1x5542 double) Feature properties: Name: {1x128 cell}
Get the size of the mapshape vector.
sz = size(ms)
sz = 1×2
