Alginates, as well, are a family of linear binary co-polymers extracted from marine brown algae, and their plant-derived sources are able to provide micro-environments similar to those presented by the ECM. In recent years, various alginate-based porous 3D scaffolds were generated for potential...
If the variable names are not valid, then you can convert them by using the matlab.lang.makeValidName function. The formula does not indicate the form of the BasisFunction. Example: 'PetalLength~PetalWidth+Species' identifies the variable PetalLength as the response variable, and PetalWidth and...
