Benchmark str* methods (strjoin, erase, strsplit, startsWith) #6

Open apjanke opened 3 years ago

apjanke commented 3 years ago

FannoFlow: The most important benchmark i think is benching the str* functions with chars and cellstrs vs the string member methods [8:41 PM] FannoFlow: Like join, erase, starts with, split, etc etc [8:41 PM] FannoFlow: The container itself might have overhead, but it's the usability of the container [8:57 PM] FannoFlow: !run data = '1.21, a, 1.985, b, 1.955, c, 2.015, d, 1.885'; datasting = string(data) tcellstr = timeit(@() str2double(erase(strsplit(data, ','),lettersPattern))) tstring = timeit(@() datasting.split(",").erase(lettersPattern).double()) [8:57 PM] BOT MATLAB: datasting = 

"1.21, a, 1.985, b, 1.955, c, 2.015, d, 1.885"

tcellstr =

3.2287e-04

tstring =

2.9424e-05 [8:57 PM] FannoFlow: string ops order of magnitude faster [8:57 PM] FannoFlow: and so much cleaner to read [8:58 PM] FannoFlow: probs could be written a bit better to use more str functions [8:58 PM] FannoFlow: but thats the idea, the comparison of cellstr operations to string array operations [8:59 PM] FannoFlow: could do some big regex pattern search too or something

Got most of these in. Still need to do startsWith and endsWith.
