Looking for some help

1. When I watch the video in the YouTube, the simulink model has errors as following.

Simulink does not have enough information to determine output sizes for this block. If you think the errors below are inaccurate, try specifying types for the block inputs and/or sizes for the block outputs.

Function 'crossFast' not supported for code generation.
[More information](matlab:helpview('coder','msginfo_Coder_builtins_FunctionNotSupportedForCodeGeneration');)

Function 'velocityFromRot.m' ([#999.1561.1613](matlab:das_dv_hyperlink('DAS','id','999.1561.1613'))), line 40, column 41:
"crossFast( repmat(omega_xy_x,1,num_vectors), r_p_x )"
Launch diagnostic [report](matlab: sfprivate('eml_report_manager','open',542);).

Function call failed.

Function 'Velocity due to rotation' ([#543.69.113](matlab:das_dv_hyperlink('DAS','id','543.69.113'))), line 2, column 10:

Simulink cannot determine sizes and/or types of the outputs for block ['QuadcopterSimModel_LindiCopter/Quadcopter/Quadcopter Propulsion/Map-based propeller fixed to airframe/Velocity due to rotation'](matlab:sfprivate('sfOpenObjectBySId','QuadcopterSimModel_LindiCopter:4227:66:65:259')) due to errors in the block body, or limitations of the underlying analysis. The errors might be inaccurate. Fix the indicated errors, or explicitly specify sizes and/or types for all block outputs.

Error in port widths or dimensions. '[output ports 1](matlab:slprivate('open_and_hilite_port_hyperlink', 'hilite', ['QuadcopterSimModel_LindiCopter/Quadcopter/Quadcopter Propulsion/Map-based propeller fixed to airframe/Velocity due to rotation/V_xy_x'], 'Outport', 1);)' of '[QuadcopterSimModel_LindiCopter/Quadcopter/Quadcopter Propulsion/Map-based propeller fixed to airframe/Velocity due to rotation/V_xy_x](matlab:open_and_hilite_hyperlink ('QuadcopterSimModel_LindiCopter/Quadcopter/Quadcopter Propulsion/Map-based propeller fixed to airframe/Velocity due to rotation/V_xy_x','error'))' is a one dimensional vector with 3 elements.

2. The zip package I downloaded doesn't have plot_flight_path.m file
