Hi everyone,

I am using LTE System Level Simulator v1.8r1375. When I try to run LTE_sim_main_launcher_demo_basic.m file, I am getting parpool error in Matlab2015a. Because of the “matlabpool” command is not valid for Matlab2015a, I write ‘parpool’ command instead of ‘matlabpool’ in channelTracefactory_v1.

For example;
if config.parallel_toolbox_installed && ~parpool(‘local’) && ~config.non_parallel_channel_trace && config.tx_mode~=1

But now I have logical command error for parpool:

Starting parallel pool (parpool) using the ‘local’ profile … connected to 4 workers.
Undefined operator ‘~’ for input arguments of type ‘parallel.Pool’.

Error in phy_modeling.channelTraceFactory_v1.generate_channel_trace (line 526)
if config.parallel_toolbox_installed && ~parpool(‘local’) && ~config.non_parallel_channel_trace &&
config.tx_mode~=1

Error in LTE_init_get_microscale_fading_SL_trace (line 135)
fading_trace =
phy_modeling.channelTraceFactory_v1.generate_channel_trace(config,precoding_configs,H_0_RB,H_i_RB);

Error in LTE_sim_main (line 86)
pregenerated_ff = LTE_init_get_microscale_fading_SL_trace(LTE_config);

Error in LTE_sim_main_launcher_demo_basic (line 52)
output_results_file = LTE_sim_main(LTE_config);

What sould I do? Is this problem solved in next versions of the simulator? I look forward to your reply.

Dear Önem,

There are no such problems with the current (newest) release v1.9 Q2-2016.

Best regards,
Fjolla

I have the same problem with release v.1.9 q2-2016
i changed the matlabpool to parpool and ‘size’ to local but it give me following error:
Undefined operator ‘~’ for input arguments of type ‘parallel.Pool’.

Error in phy_modeling.channelTraceFactory_v1.generate_channel_trace (line 561)

Error in LTE_sim_main (line 93)
pregenerated_ff = LTE_init_get_microscale_fading_SL_trace(LTE_config);

output_results_file = LTE_sim_main(LTE_config);

Don’t use parpool, instead use the deprecated version. It will show warning, but at least run without error.
