Transpose of matrix (15x10) using vector of vector

[mermaidly]

Hello! I wanna display the transpose of a (15x10) matrix but I'm encountering a few errors that I can't seem to fix. Here are my progress so far

  #include <iostream>
#include <vector>

using namespace std;

void generarMatriz(vector<vector<int> > &m){
    cout << "Introduce los valores de la matriz ordenados por fila y columna: " << endl;
    for (int i = 0; i < m.size(15); i++)//rows
        for (int j = 0; j < m[0].size(10); j++){//columns
            cout << "Introduce el valor de la fila " << i << " y columna " << j << " : ";
            cin >> m[i][j];
        }

}

void escribirMatriz(vector<vector<int> > &m){
    for (int i = 0; i < m.size(15); i++){
        for (int j = 0; j < m[0].size(10); j++)
            cout << m[i][j] << "\t" ;
        cout << endl;
    }
    cout << endl;
}

void transponer (vector<vector<int> > transponer(vector<vector<int> > &m)){
    vector<vector<int> > nueva(m[0].size(10),vector<int>(m.size(15),0.0));
    for ( int i = 0 ; i < m.size(10) ; i++ ){
        for ( int j = 0 ; j < m[0].size(15) ; j++ )
            nueva[j][i] = m[i][j];

    m = nueva;

    }

}



int main()
{

vector <vector<int> > m1(kMAXDIM,vector<int> (kMAXDIM)),
                             m2(kMAXDIM,vector<int> (kMAXDIM)),
                             result(kMAXDIM,vector<int> (kMAXDIM));


        generarMatriz(m);
                cout << "Matriz inicial: " << endl;
                escribirMatriz(m);
                transponer(m);
                cout << "Matriz transpuesta " << endl;
                escribirMatriz(m);



    return 0;
}

Here are the erorrs:

|8|error: no matching function for call to 'std::vector<std::vector<int> >::size(int)'|
|9|error: no matching function for call to 'std::vector<int>::size(int)'|

m.size(15)

The vector::size() method is nullary. It doesn't take any parameters. Here you pass it an int, which is why you are getting an error.

So how do i form a 15x10 matrix since it's not a square matrix?

[Ganado]

You already formed a matrix (vector of vectors) on line 42, 43, 44.

Your main function does not have a variable called m.
You have m1, m2, result defined.

The size() method of vector doesn't take any arguments, as Toaster already said.
(Requiring a size function to take in a size would defeat the purpose of a size function...)

Edit: You also don't have kMAXDIM defined.
if you want one dimension to be different than the other dimension, then you want something like:
vector<int>(rows, vector<int>(columns))

[TheToaster]

You need to first initialize the vector with 15 subvectors, who have a size of 10:

std::vector<std::vector<int>> a{15, std::vector<int>(10)};

[mermaidly]

 #include <iostream>
#include <vector>

using namespace std;


void generarMatriz (vector<int> a{15,vector<int>(10))}){

    cout << "Introduce los valores de la matriz ordenados por fila y columna: " << endl;
    for (int i = 0; i < m.size(); i++)//rows
        for (int j = 0; j < m[0].size(); j++){//columns
            cout << "Introduce el valor de la fila " << i << " y columna " << j << " : ";
            cin >> m[i][j];
        }

}

void escribirMatriz (vector<int> a{15,vector<int>(10)}){
    for (int i = 0; i < m.size(); i++){
        for (int j = 0; j < m[0].size(); j++)
            cout << m[i][j] << "\t" ;
        cout << endl;
    }
    cout << endl;
}

void transponer (vector<vector<int> > transponer(vector<vector<int> > &m)){
    vector<vector<int> > nueva(m[0].size(),vector<int>(m.size(),0.0));
    for ( int i = 0 ; i < m.size() ; i++ ){
        for ( int j = 0 ; j < m[0].size() ; j++ )
            nueva[j][i] = m[i][j];

    m = nueva;

    }

}



int main()
{

vector <vector<int> > m1(kMAXDIM,vector<int> (kMAXDIM)),
                             m2(kMAXDIM,vector<int> (kMAXDIM)),
                             result(kMAXDIM,vector<int> (kMAXDIM));


        generarMatriz(m);
                cout << "Matriz inicial: " << endl;
                escribirMatriz(m);
                transponer(m);
                cout << "Matriz transpuesta " << endl;
                escribirMatriz(m);



    return 0;
}

Errors:
|7|error: expected ')' before '{' token|
|7|error: expected ';' before ')' token|
|7|error: expected unqualified-id before ')' token|

Edit:
Aside from the mismatching ( {, }, ), that's not how you pass a vector to a function.

Do:
void myFunction(vector<vector<int>>& m) { ... }

Yes, it looks horrible. (This is one reason why I tend to avoid multi-dimensional vectors or arrays)

[jonnin]

consider making your vector<vector<thing>> a type masked name.
consider passing nueva into the function as a reference to save a copy. then just directly assign the result in the loop. The extra copy can be avoided entirely in a number of ways saving time.

you cannot do the initialize in the function parameter list. you have to do it before the function is called or inside the function.

[mermaidly]

Can you guys help me out and edit my codes. I've been working on it for 12 hours I'm losing my mind T_T

[TheToaster]

This is how your function headers should look like:
void generarMatriz (vector<vector<int>>& a)

This is how you should pass it in main()

vector<vector<int>> m1{15, std::vector<int>(10)}, m2{15, std::vector<int>(10)}, result{15, std::vector<int>(10)};

generarMatriz(m);
//...
