This is related to the matlab user guide: 5G library for LTE system toolbox. I have generated the PDSCH and DMRS symbols and their respective indices, now I need to map them to the slot grid and perform precoding->CP-OFDM. I was wondering if there's any matlab command for 'Map to slot grid' or if not, how can we map the PDSCH data and DMRS symbols onto the resource blocks.

'Map to slot grid' just means using the MATLAB assignment operation i.e.
slotgrid(pdschindices) = pdschsymbols; slotgrid(pdschdmrsindices) = pdschdmrssymbols;
The RE indices are 1-based, linear indices of the normal MATLAB array indexing format.
You'll see this assignment in the link throughput example, included in the 5G Library.

Hi there,
Check out the new 5G Toolbox, released for R2018b.
