No, thank you.
It depends on the type of matrices you want to know. There are different ways to do different types.
Like the quality answer of many of these kinds of questions: Practice a lot.
Matrices can't be "computed" as such; only operations like multiplication, transpose, addition, subtraction, etc., can be done. What can be computed are determinants. If you want to write a program that does operations such as these on matrices, I suggest using a two-dimensional array to store the values in the matrices, and use for-loops to iterate through the values.
Only square matrices have inverses.
I suggest asking separate questions for complex numbers, and for matrices. Complex numbers are used in a variety of fields, one of them is electrical engineering. As soon as AC circuits are analyzed, it turns out that complex numbers are the natural way to do this.
how is matrices is applicable in our life?
The matrices must have the same dimensions.
Only square matrices have a determinant
The singular form of matrices is matrix.
There are no matrices in the question!
In mathematics matrices are made up of arrays of elements.
I do not. I f*cking hate matrices. I multiply sheep.
