Missing DLLs when running exampleAreaPlot

[radioflyer28]

I installed R2019a 64-bit in an attempt to get the MEX function accumarraymax_mex to run (since I was on 2020b which would've required re-compiling the mex functions). I have the needed addons installed (coder, mapping toolbox, statistics toolbox).

However, upon running the example code exampleAreaPlot in R2019a, the function accumarraymax_mex wants DLLs that are unavailable. These DLLs are:

• icudt61.dll
• icuuc61.dll
• icuin61.dll
• libmwi18n.dll
