IF you use **Juno**?

```julia
#CPUtic()
function testInv(n)
    MM = rand(Float64,n,n)
   mmm = inv(MM)
end

 @time testInv(10000);

```

> 47.049461 seconds (2.82 k allocations: 1.495 GiB, 0.36% gc time)

Matlab

```julia

tic()

MM=rand(10000,10000);
mmm=inv(MM);

toc()
Elapsed time is 23.070654 seconds.

```

Jupyter

```julia

 43.998483 seconds (1.19 M allocations: 1.552 GiB, 0.19% gc time)
