    Syntax

    B = gpucoder.ctranspose(A)

    Description

    B = gpucoder.ctranspose(A) performs efficient out-of-place conjugate transpose on the GPU using shared memory. When called from MATLAB® (out of the code generation context), gpucoder.ctranspose calls the built-in ctranspose function.

    This example generates CUDA® code to transpose a matrix.

    In one file, write an entry-point function myTranspose that accepts a matrix input A. Use the gpucoder.ctranspose function to generate a GPU efficient implementation for transposing A.

    function B = myTranspose(A)
     B = gpucoder.ctranspose(A);
end

    Use the codegen function to generate CUDA MEX function.

    input = complex(ones(1024,1024,'double'),ones(1024,1024,'double'));
codegen -config coder.gpuConfig('mex') -args {input} -report myTranspose
