example code is:
gn = rand(1000,"gpuArray")/100 + 0.995;
offs = rand(1000,"gpuArray")/50 - 0.01;
meas = ones(1000)*3; % 1000-by-1000 matrix
corrected = arrayfun(@MC_OceanLidar_sub,meas,gn,offs);
results = gather(corrected);
function c = test(rawdata, gain, offset)
layer=1:0.2:100;
c = (rawdata .* gain) + offset + max(layer);
end
the error message is:
Function passed as first input argument contains unsupported or unknown function 'test'.
or
function c = test(rawdata, gain, offset)
layer=NaN(10000,1,'single');
c = (rawdata .* gain) + offset + max(layer);
end
the error message is :
Size inputs are not supported when using 'NaN'. Input to 'NaN' must be a valid class specification such as 'single' or 'double', or the
word 'like' followed by a prototype argument.

You cannot create an array inside a call to GPU arrayfun, only scalars.
