GLSL built-in function
transpose()
Swaps matrix rows and columns.
Demo version: GLSL ES 3.00 / WebGL 2Demo stage: Fragment
Syntax
mat transpose(mat m)Parameters
- m
- Input declared in the signature; match its type and dimensions
Return value
A matrix with rows and columns exchanged; result[column][row] equals m[row][column].
Live example

What transpose does
Swaps matrix rows and columns.
Read the preview
Transposing mat2(1.0,0.6,0.0,1.0) moves the shear coefficient to the other off-diagonal position. Set 0.6 to 0.0 to see the grid return to square alignment.
Core call
transpose(mat2(1.0,0.6,0.0,1.0))*vec2(x,y);
GLSL matrix constructors are column-major; transpose changes the shear direction.
Experiment
Replace transpose(mat2(1.0,0.6,0.0,1.0)) with the matrix itself. The grid shears along the other coordinate, exposing the row/column swap.
