SplitApply Combine Analysis. Data often contains sub-groups that are distinguishable based on one or more (usually) categorical variables. For example, the iris R built-in data set has a Species variable that allows you to separate the data into groups by species. A common analysis for this type of data with groups is to run a computation on each group. str = compose (formatSpec,A) formats data values from the input array, A, using formatting operators specified by formatSpec and returns the resulting text in str. The compose function formats values from A in column order. If formatSpec is a string array, then so is the output array str. Otherwise, str is a cell array of character vectors. Introducing two new functions. Our tireless MATLAB developers keep adding great new functionality for data analysis. I've been having fun playing with two new functions introduced in R2015b: findgroups and splitapply.These functions make it easy to find all unique combinations of key variables, assign a group number to each observation in your data based on those key variables, then apply a.

I have data in a matlab table in long format. It contains stock tickers and monthly returns. I'd like to group the data by tickers, than grab the next periods return, and make a column of that next periods return. Here is my code. It returns cell arrays for each group. matlab apply function to each rowgain on sale of equipment journal entry "Where Quality Control is Job 1" what major tournament is played on a clay surface? california discovery verification form; spexlite shooting bag fills; can bacterial infection cause irregular periods;. function rowvec = myfunc (Table) Suppose I have a master table, call it T with one of its variables being Name. I'd like to do something like the following to group by Name and concatenate rowvec computed from each subgroup: G = findgroups (T.Name); R = splitapply (@myfunc,T,G); This won't work because splitapply sends the group of each.

Find the max value and index of each interval in... Learn more about unique splitapply. The following introduction comes from "Making and Printing Plots in MATLAB," which was formerly an appendix to the EGR 103 lab manual. Information contained within this particular section may be modified or move as deemed appropriate. The plot function is used to plot sets of data on a 2-D grid. What follows comes from MATLAB's help function in MATLAB R2009a[1] (some paragraphs have been snipped out). The line styles, symbols, and colors are formatted as a clearer table.

function rowvec = myfunc (Table) Suppose I have a master table, call it T with one of its variables being Name. I'd like to do something like the following to group by Name and concatenate rowvec computed from each subgroup: G = findgroups (T.Name); R = splitapply (@myfunc,T,G); This won't work because splitapply sends the group of each. splitapply uses the group numbers to split the data into groups efficiently before applying a function.

The splitapply function uses G to split T.Loss into five groups, corresponding to the five regions. splitapply applies the max function to each group and concatenates the maximum power losses into a vector. G = findgroups (T.Region); maxLoss = splitapply (@max,T.Loss,G) Calculate the maximum power loss due to a power outage by cause. If I use splitapply on functions with only one argument, it seems to do what I expect: >> splitapply(@sum,[1,1;2,3],1:2) ans = 3 4 I would be glad if someone could point out what is happening.
