## Methods

Method	Modifiers	Description
[castToBaseType()](./rc-js-util.mat4.casttobasetype.md)		Although the typed array tuples extend a typed array, they are not structurally compatible. This function returns the argument passed without modification but cast as the underlying storage type, e.g. Float32Array.
[copyFromBuffer(\_memoryDataView, \_pointer, \_littleEndian)](./rc-js-util.mat4.copyfrombuffer.md)		If endianness is not supplied the platform's endianness will be used.
[copyToBuffer(\_memoryDataView, \_pointer, \_littleEndian)](./rc-js-util.mat4.copytobuffer.md)		If endianness is not supplied the platform's endianness will be used.
[getCtor(ctor)](./rc-js-util.mat4.getctor.md)	`static`
[getLoggableValue()](./rc-js-util.mat4.getloggablevalue.md)
[getRow(\_row, \_writeTo)](./rc-js-util.mat4.getrow.md)
[getValueAt(\_column, \_row)](./rc-js-util.mat4.getvalueat.md)
[isEqualTo(\_other)](./rc-js-util.mat4.isequalto.md)		Component-wise equals.
[setIdentityMatrix()](./rc-js-util.mat4.setidentitymatrix.md)
[setRow(\_row, \_writeFrom)](./rc-js-util.mat4.setrow.md)
[setValueAt(\_column, \_row, \_value)](./rc-js-util.mat4.setvalueat.md)
