How to convert and use the GLSL mat2 type to its equivalent in RenderScript

Question

What is the equivalent conversion of the glsl mat2 type in Renderscript and how to use it?

I came to the conclusion that it may be rs_matrix2x2, but I can't find any sample code about how to use it.

I 'm trying to convert the next GLSL snippet into RenderScript:

GLSL:

vec2 test(vec2 coord, float c, float s)
{
    mat2 m = mat2(c, -s, s, c);
    return m * coord;
}

Rendercript:

float2 test(float2 coord, float c, float s)
{
    //???? -> mat2 m = mat2(c, -s, s, c);
    return m * coord;
}

Just found the solution. In case is of any use to others, here is the conversion and usage based in the sample snipped in the question:

float2 test(float2 coord, float c, float s)
{
    rs_matrix2x2 m = {c, -s, s, c};
    return rsMatrixMultiply(&m, coord);
}
