Solved: load value inside job

Sure, I’ll put together a detailed analysis of how to load values in MATLAB while intertwining some catchy fashion tidbits. Here we go:

Load Value in MATLAB: A task as sophisticated as an iconic fashion couture

Just like every fashion style has a story behind its origin, development in programming also has its roots deepened into problem-solving strategies. One such common issue faced by many MATLAB programmers is loading a value inside a job.

In the riveting world of haute couture, trends appear and disappear, but the essence always remains. Similarly, in the MATLAB universe, despite the evolution of technical methodologies, the need for loading objects for workers to utilize persistently remains valid. The load function in MATLAB enables us to bring data back into the environment, proving particularly valuable when working with big datasets in batch processing.

A Solution as Enviable as the Little Black Dress

The primary method to resolve this problem involves creating a parallel job, adding tasks to it, assigning an object to a job data slot, and then retrieving it from the workers in a task function. The solution could be seen as an equivalent to the all-time-fashion-favorite Little Black Dress, a simple yet efficient solution suitable for all situations.

 
% create cluster
clust = parcluster('local');
 
% create job
job = createJob(clust);
 
% assign your data to a Job Data slot
job.JobData.MyData = magic(10);
 
% add task
createTask(job, @mysum, 1, {});
 
% run job
submit(job);
waitForState(job);
 
% retrieve data
MyData = job.JobData.MyData;

Juxtaposing the snippet above with fashion, the code is an ensemble, every line working together to solve the problem — much like every piece of a carefully curated outfit contributing to a stunning ensemble.

The High-Fashion Runway Walk-Through of the MATLAB Code

Just as every masterpiece from the great fashion houses requires attention to detail, understanding this MATLAB code also demands a thorough step-by-step walkthrough.

 
clust = parcluster('local');
  • This line is like selecting the perfect fabric for our fashion creation. It initiates a parallel computing setup by creating a cluster object.
    • job = createJob(clust);
  • Creating a parallel job is like sketching our fashion design onto a mannequin. Here, we create a job that operates on the cluster previously defined. 
    • job.JobData.MyData = magic(10);
  • This is analogous to selecting embellishments to adorn our garment. We assign a 10×10 magic square matrix to MyData field of JobData.
    • createTask(job, @mysum, 1, {});
  • Adding a task to the job is like finalizing details of our fashion design before it’s showcased. In this case, the task to sum the matrix is introduced.
    • submit(job); 
waitForState(job);
  • The ‘submit’ function sends off the job to be executed much like a model sashaying down the runway. The ‘waitForState’ waits for the job to finish, akin to the anticipation before the jury’s verdict.
    • MyData = job.JobData.MyData;
  • The final line collects the result of computation, similar to the applause from the audience admiring the finished attire on the catwalk. The calculated sum matrix is retrieved.

Essence of MATLAB functions and fashion libraries:

In conclusion, just like how a fashion designer uses various techniques, textures, and layers to create a stunning outfit, as a programmer, the incorporation of functions such as ‘createJob’, ‘createTask’, and ‘submit’, and concepts of MATLAB parallel computing can piece together a perfect solution. A programmer is, after all, a designer of solutions, and every line of code they knit brings us one step closer to the future. A creator in their own unique way, whether they design runway-worthy fashion or groundbreaking software!
