WebGL2RenderingContext：uniformMatrix[234]x[234]fv() 方法
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2021年9月.
* Some parts of this feature may have varying levels of support.
备注： 此特性在 Web Worker 中可用。
WebGL 2 API 的 WebGL2RenderingContext.uniformMatrix[234]x[234]fv() 方法用于为 uniform 变量指定矩阵数值。
备注：
此方法并没有真正名为 2x2、3x3 和 4x4 的版本，它们分别被简写为 2、3 和 4。请参阅下方语法说明。

参数
location-
WebGLUniformLocation对象，包含要修改的 uniform 属性的位置。 transpose-
GLboolean，用于指定是否对矩阵进行转置。 data-
一个由浮点数组成的
Float32Array。
返回值
无（undefined）。
示例
js
gl.uniformMatrix2x3fv(loc, false, [1, 2, 3, 4, 5, 6]);
