What a "user-friendly" application! This was my first impression when I first installed Matlab on my computer and it started up with a screen with a command prompt and basically nothing else. But I gradually began to appreciate the flexibility and power of data analysis and the relative ease of programming of Matlab. I wrote Matlab code for fun and for developing applications for myself or for my colleagues. Below, you can find a selection of the utilities I developed.
You can fit a regression line on 2D histogram data, i.e. if you already don't have the original data set containing two measurements for each data point.
Help is available by typing "help regressContourPlot" at the Matlab command prompt.
A trend line can be created from a data set containing two measurements for each data point. In order to create a trend line the X range is divided into the specified number of bins and the mean of the Y variable in each bin is calculated.
Help is available by typing "help createTrend" at the Matlab command prompt.
You can generate a 2D histogram (contour plot) interactively from a dataset containing two measurements for each data point.
Help is available by typing " help createContour" at the Matlab command prompt.
The program fits the Hill equation to measurement data. The Hill equation has the following forms depending on whether IC50 or EC50 is fitted on concentrations on a linear or logarithmic scale:
The program can be run in GUI mode or command-prompt mode.
The following parameters are followed by two numbers:
|Parameter name||Value of first parameter||Value of second parameter|
|ic50||1=to fit, 0=fixed parameter||if first parameter is 1 -> initial value
if first parameter is 0 -> value of the fixed parameter
|ec50||same as above||same as above|
|n||same as above||same as above|
|min||same as above||same as above|
|max||same as above||same as above|
If 'ec50' and 'ic50' is not followed by a numeric parameter, it only specifies whether a decreasing or increasing curve is to be fitted.
The following parameters are followed by one number or variable:
The following parameters aren't followed by anything:
The program upgrades itself.
