# Is Scilab better than octave?

## Is Scilab better than octave?

SciLab and Octave are preferred by engineers and students but the stream of preference is different. While mechanical, manufacturing, and industrial engineers prefer for SciLab, Octave is preferred by IT students for their programming skills and various features related to OOPS programming in the software.

**Is Scilab faster than Matlab?**

MATLAB is very fast when performing matrix multiplications since it uses the multithreaded BLAS subroutines from the Intel Math Kernel Library (MKL). MATLAB is better than Scilab and python.

### Is modelica better than Simulink?

Another big advantage of modelica is the Medium way of calculating fluid properties. The function approach in Simulink and the object oriented medium method in Modelica essentially calculate the same set of properties but the medium approach is exponentially more easier and much more stable.

**Can you use OpenModelica as an alternative to MATLAB?**

The short answer is yes, OpenModelica can be used as an alternative. The long answer is that things are not that easy. OpenModelica is not yet at the Simulink/Matlab level of robustness, scalability and ease-of-use.

## Are there any differences between MATLAB and Scilab?

They correspond to the Boolean statements ‘true’and ‘false’, respectively. Indexing with Boolean variables may not produce the same result in SCILAB as it does in Matlab® . For example x=[1,2];x([1,1])[which is NOT x([%T,%T])]returns [1,1]in SCILAB and [1,2]in Matlab®. Also if x is a matrix x(1:n,1)=[] or x(:)=[]are not valid in Matlab®.

**How are functions defined in Scilab and MATLAB?**

Functions Functions in SCILAB are not considered as separate files, such as Matlab® m-files, but as variables in the SCILAB environment. One or several user-defined functions can be defined in a single file, and the name of the file is not necessarily related to the name of the function(s).

### How are polynomials defined in Scilab and MATLAB?

Polynomials and polynomial matrices are defined by the function poly in SCILAB. They are considered as vectors of coefficients in Matlab®. For more details on SCILAB polynomials see Chapter 8 in this book. []+1 returns 1 in SCILAB and [] in Matlab®.
