FitData1D#

class FitData1D(rawData)#

Bases: FitData

FitData1D abstract base for one-dimensional data fitting.

Extends FitData to provide specialized functionality for fitting functions to 1D data (x,y coordinate pairs). Includes plotting capabilities and fit evaluation methods (evaluateFit()).

Example1:

% Create and perform a 1D fit
x = linspace(0, 10, 100);
y = 2*exp(-(x-5).^2/2) + 0.1*randn(size(x));
data = [x', y'];
fitObj = GaussianFit1D(data);
fitObj.do();
fitObj.plot();

Example2:

% Evaluate fit at specific points
fitObj = LinearFit1D(data);
fitObj.do();
xEval = [1, 2, 3, 4, 5];
yEval = fitObj.evaluateFit(xEval);

Constructor Summary

FitData1D(rawData)#

Construct a FitData1D.

Parameters:: rawData (double array) – Input data as n x 2 matrix [x, y]

Property Summary

DataSize (1,1) double#: Number of data points

FitPlotData (:,2) double#: n * 2 array for plotting fit curve

Method Summary

checkData(rawData)#

Validate input data format for 1D fitting.

Parameters:: rawData (double array) – Input data to validate
Returns:: Validated data or empty array
Return type:: double array

do()#

Perform the fitting operation.

Returns:: Self-reference for method chaining
Return type:: FitData1D

evaluateFit(x)#

Evaluate the fitted function at specified x values.

Parameters:: x (double array) – x-coordinates for evaluation
Returns:: y-values from fitted function
Return type:: double array

plot(targetAxes, isRender)#

Plot raw data and fit curve.

Parameters:

targetAxes (axes handle) – Target axes for plotting (optional)
isRender (logical) – Whether to render axis labels and formatting

Example:

fitObj.plot();
fitObj.plot(gca, false);
