Maximum variable size allowed by the program is exceeded. FOR OCDM MODULATION

i need a help plzzzz !
i would have the OCDM modulation BER SNR figure for 64 QAM
so had a problem at this point, matlab give me this problem : Maximum variable size allowed by the program is exceeded.
here is the code :
