Fixed-Price - Est. Budget: $ 60 Posted
Overview: I need help with speeding up five similar self-written Matlab functions. In the /program/ folder, I have a master file which loads the input data sets, and calls these five functions many times. In this test task, I would like you to help me speed up one function, epdvfct_2pln_RC20yrCeps Tasks: Profiler shows that the three dimensional matrix operations in the inner loop of each function are very slow. Vectorization might improve the speed considerably. Coding some loops more efficiently may also improve speed. Since I am not very experienced with Matlab, I might have written some parts of the programs inefficiently, so you can also help me re-write those parts to make the programs more efficient. Therefore, I would like you to (1) vectorize the 3 dimension matrix operations where possible; (2) optimize the loops (ex. vectorize them); (3) Improve efficiency of the programs where possible; (4) keep a clear documentation of what changes you make and why. Deadline: This is...

Hi Upworkers! I recently finished building an online store that aims to showcase some of the best tea-related products Amazon, and now I'm looking for a Virtual Assistant/Content Manager/Producer to help me make it a real success. The online store has been built on Wordpress and uses Woocommerce, a custom theme, several different plugins, including one that helps with importation of products from Amazon. Initially, I'm looking for someone to work 2 hours a day, 5 days a week, ongoing. Your daily responsibilities would be to: - Build out tea related categories, filters, etc. - Import a selection of products from Amazon into the store. For example, could be top reviewed Chai teas. (Most of this process is automated.) - Fix any issues with product imagery due to the importation process. (Images can be cropped incorrectly and/or the order might be wrong) - Make sure each product is assigned to the right categories andhas a SEO/site friendly product title. (Some titles...

I have a web platform which allows users to visually connect media clips together via drag & drop canvas. You click one media file and the click the 2nd file and a dynamic, directional line is created connecting them. However the javascript library (Raphael.js) we are using is antiquated and starts to break up after several connections are made or if a connected clip is moved they may all start to move. Please see the attached image I need a new library integrated, or code developed, that replicates the original planned behavior but is more reliable and does not break up. I think D3.js is likely a solution but am open to other suggestions. Am ready to get this started immediately, ie. today. Please send examples of similar/data visualization work. Thank you
