RE: [QUESTION] command names on History & CAS MODE VIEW
The double functionality is valid and I agree
ABS vs abs The problem is only visualization within the history view with "Textbook Display on" & ALGEBRAIC input mode Because copying the expression to the input line is renamed. Please try the following Enable the ALGEBRAIC input mode & "Textbook Display off" abs([a,b]) → [abs(a), abs(b)] // ok [up][up][copy] abs([a,b]) → [abs(a), abs(b)] // ok but Enable the TEXTBOOK input mode & "Textbook Display off" abs([a,b]) → ABS([a,b]) → √(a^2+b^2) This is not logical, the same input two different answers Another case CAS MODE MAKEMAT(0,10); -> Error: Bad Argument Type" Why? makemat(0,10); ->[[0,0,0,0,0,0,0,0,0,0]] makeMat(0,10); -> [0,0,0,0,0,0,0,0,0,0]; // ok =) mat1:=makeMat(0,10); -> [0,0,0,0,0,0,0,0,0,0]; // ok =) mat1(1):=a; -> [a,0,0,0,0,0,0,0,0,0]; // ok =) mat1(10):=j; -> [a,0,0,0,0,0,0,0,0,j]; // ok =) mat1[2]:=b; -> [a,b,0,0,0,0,0,0,0,0]; // ok =) mat1[2]; -> b // ok mat1(2); -> b // ok dim(mat1); -> 10 // ok DIM(mat1); -> {10} // ok DIM(mat1)[1]; -> 10 // ok DIM(mat1)(1); -> 10 // ok MAKELIST(0,X,1,10); -> {0,0,0,0,0,0,0,0,0,0} // ok makelist(0,X,1,10); -> [0] Why? makeList(0,X,1,10); -> Error: Bad Argument Type" Why? list1:=MAKELIST(0,X,1,10) -> {0,0,0,0,0,0,0,0,0,0} // ok dim(list1); -> 10 // ok DIM(list1); -> {1,1,1,1,1,1,1,1,1,1} // ok mat0:=MAKEMAT(0,3,4) -> [[0,0,0,0],[0,0,0,0],[0,0,0,0]] // ok HOME DIM(mat1) -> {10} dim(mat1) -> {10} DIM(mat1)[1] -> {[10]} -> 10 DIM(mat1)(1) -> {10} ? inside program (HOME) local elements:=dim(mat1)[1]; // error or local elements:=dim(mat1)(1); // error for aux_index_i from 1 to dim(a)[1] do // error |
