MATLAB to Python Mapping#

This note maps the original MATLAB FemLab toolbox under FemLab_matlab/M_Files/ to the current femlabpy package layout.

Core Utilities#

MATLAB	Python
`init.m`	`femlabpy.core.init`
`rows.m`, `cols.m`	`femlabpy.core.rows`, `femlabpy.core.cols`
`assmk.m`, `assmq.m`	`femlabpy.assembly.assmk`, `femlabpy.assembly.assmq`
`setload.m`	`femlabpy.loads.setload`
`setbc.m`	`femlabpy.boundary.setbc`
`reaction.m`	`femlabpy.postprocess.reaction`
`rnorm.m`	`femlabpy.boundary.rnorm`
`setpath.m`	`femlabpy.compat.setpath`

Material Helpers#

MATLAB	Python
`devstres.m` / `devstress`	`femlabpy.materials.devstress` and alias `femlabpy.devstres`
`eqstress.m`	`femlabpy.materials.eqstress`
`yieldvm.m`	`femlabpy.materials.yieldvm`
`dyieldvm.m`	`femlabpy.materials.dyieldvm`
`stressvm.m`	`femlabpy.materials.stressvm`
`stressdp.m`	`femlabpy.materials.stressdp`

Element Kernels#

MATLAB	Python
`kebar.m`, `qebar.m`, `kbar.m`, `qbar.m`	`femlabpy.elements.bars`
`ket3e.m`, `qet3e.m`, `kt3e.m`, `qt3e.m`	`femlabpy.elements.triangles`
`ket3p.m`, `qet3p.m`, `kt3p.m`, `qt3p.m`	`femlabpy.elements.triangles`
`keq4e.m`, `qeq4e.m`, `kq4e.m`, `qq4e.m`	`femlabpy.elements.quads`
`keq4p.m`, `qeq4p.m`, `kq4p.m`, `qq4p.m`	`femlabpy.elements.quads`
`keq4eps.m`, `qeq4eps.m`, `kq4eps.m`, `qq4eps.m`	`femlabpy.elements.quads`
`keq4epe.m`, `qeq4epe.m`, `kq4epe.m`, `qq4epe.m`	`femlabpy.elements.quads`

Plotting and Mesh I/O#

MATLAB	Python
`plotelem.m`	`femlabpy.plotting.plotelem`
`plotq4.m`	`femlabpy.plotting.plotq4`
`plott3.m`	`femlabpy.plotting.plott3`
`plotu.m`	`femlabpy.plotting.plotu`
`load_gmsh.m`, `load_gmsh2.m`	`femlabpy.io.gmsh.load_gmsh`, `femlabpy.io.gmsh.load_gmsh2`

The Gmsh loaders now expose both the normalized Python mesh fields (positions, triangles, element_infos, …) and the legacy MATLAB aliases (POS, TRIANGLES, ELE_INFOS, nbTriangles, MIN, MAX, …).

Original Example Coverage#

MATLAB example	Python entry point
`canti.m`	`femlabpy.examples.run_cantilever`
`flow.m` + `flowq4.m`	`femlabpy.examples.run_flow_q4`
`flow.m` + `flowt3.m`	`femlabpy.examples.run_flow_t3`
`bar01.m` + `nlbar.m`	`femlabpy.examples.run_bar01_nlbar`
`bar02.m` + `nlbar.m`	`femlabpy.examples.run_bar02_nlbar`
`bar03.m` + `nlbar.m`	`femlabpy.examples.run_bar03_nlbar`
`square.m` + `plastps.m`	`femlabpy.examples.run_square_plastps`
`square.m` + `plastpe.m`	`femlabpy.examples.run_square_plastpe`
`hole.m` + `plastps.m`	`femlabpy.examples.run_hole_plastps`
`hole.m` + `plastpe.m`	`femlabpy.examples.run_hole_plastpe`

The nonlinear and plastic drivers now live in femlabpy.solvers, and the example inputs needed for installed-package parity are packaged under femlabpy.data.cases.

MATLAB Compatibility Aliases#

The package also exposes the original classroom script names as documented Python wrappers with explicit arguments:

MATLAB name	Python compatibility wrapper
`canti`	`femlabpy.canti()`
`flow`	`femlabpy.flow()`
`flowq4`	`femlabpy.flowq4()` or `femlabpy.flowq4(T1, X, G, C, P=None, dof=1)`
`flowt3`	`femlabpy.flowt3()` or `femlabpy.flowt3(T2, X, G, C, P=None, dof=1)`
`bar01`, `bar02`, `bar03`	`femlabpy.bar01()`, `femlabpy.bar02()`, `femlabpy.bar03()`
`square`, `hole`	`femlabpy.square()`, `femlabpy.hole()`
`elastic`	`femlabpy.elastic(...)`
`nlbar`	`femlabpy.nlbar(...)`
`plastps`, `plastpe`	`femlabpy.plastps(...)`, `femlabpy.plastpe(...)`

These wrappers are designed for help() / docstring discovery and for users coming directly from the original MATLAB notes. Internally they call the vectorized femlabpy kernels and solvers.
